PRODUCT OVERVIEW 1PARTFor more than 40 years, Compuware has been producing high-quality Storage Management Software. Over the years, its products have evolved into today’s ultra high-speed, safe, reliable storage management solutions for z/OS and non-z/OS data.

It all started with the FDR Storage Management Family, for which thousands of licenses have now been sold worldwide. The FDR Family is the complete Storage Management System for z/OS.

FDR has become the industry standard for fast, reliable backups of z/OS data, while ABR adds a layer of automation to the standard functions of FDR, providing advanced backup facilities like Incremental Backup, Application Backup and Archiving.

FDRINSTANT provides near 24x7 backup of offline volumes created by DASD Subsystem features like Oracle SnapShot Copy, EMC TimeFinder, Hitachi ShadowImage and IBM FlashCopy. FDRINSTANT also enhances the performance of other utilities in the FDR Family, such as FDRCOPY and FDRMOVE.

FDRCRYPT offers encryption services for all FDR and ABR backups, as well as sequential output created by an IDCAMS REPRO. FDRCRYPT protects these backups against unauthorized access by anyone who does not possess the proper encryption keys.

FDRDRP is an extension of ABR that can reduce full-volume recovery time by up to 80%.

FDRPAS and FDRMOVE provide non-disruptive or minimally disruptive movement of data from one disk to another, either within the same disk subsystem or across different subsystems. Data can be moved non-disruptively at the volume level (with FDRPAS), or it can be moved non-disruptively or with minimal disruption at the data set level (with FDRMOVE). These products are particularly useful for migrating and/or consolidating data from smaller disks to larger disks (e.g. 3390-3s to 3390-9/27/54s and EAVs).

COMPAKTOR and FDRREORG offer intelligent and powerful reorganization processes for whole DASD volumes and for PDS, VSAM and IAM data sets.

FDREPORT and FDRViEWS provide extensive, customized DASD Management Reporting to suit many needs and purposes. You can run your reporting as a z/OS batch job or through TSO/ISPF panels with FDREPORT, or you can use a Windows-based user interface available through FDRViEWS.

FDRERASE V5.4 L70 is an EAL2++ certified product that can be licensed as an option to FDRPAS (or separately). It can quickly and securely erase many z/OS disk volumes in parallel, allowing you to erase your data in the minimum elapsed time. Multiple levels of erasure are available.

PRODUCT OVERVIEW 1PARTIAM, FATS/FATAR and FATSCOPY complete Innovation’s z/OS product range:

IAM is Innovation’s alternative to VSAM KSDS, ESDS and (as a cost option) AIX and RRDS files. IAM consistently provides 50-80% reductions in EXCPs, Batch Elapsed Times and Online Response Times, as well as a 20-40% reduction in CPU usage compared to VSAM. Due to its advanced file structure, IAM typically requires 30-70% less DASD space than VSAM to hold the same amount of data.

IAM/PLEX is a cost option to IAM that provides z/OS SYSPLEX Record Level Sharing (RLS) for IAM data sets across multiple z/OS systems and LPARs that are connected as a z/OS SYSPLEX.

FATS/FATAR is a set of multi-purpose tape subsystem Media Integrity tools that allow for online tape certification, verification, analysis and erasure of tapes.

FATSCOPY provides automated tape stacking and conversion, including Tape-to-VTS, VTS-to-Tape and VTS-to-VTS conversions.

The UPSTREAM family builds on the strengths of the FDR Storage Management system, and extends Innovation’s range of products beyond the boundaries of z/OS:

FDR/UPSTREAM provides a fast, safe and reliable solution to backing up Open Systems data that resides on file servers and workstations. Backups are transmitted across a network connection to disk or tape on the z/OS host.

FDR/UPSTREAM Linux on System z offers a high performance solution for backing up your Linux on System z clients.

FDR/UPSTREAM z/OS UNIX supports file level data protection for z/OS UNIX including HFS and zFS systems.

FDRSOS and UPSTREAM/SOS provide additional performance enhancements to the backup and restore process, which can utilize high-performance System z FICON channels if the Open Systems data is resident on an IBM DS8700/DS8800 with zDDB, or an EMC Symmetrix DMX or VMAX with z/SOS (formerly Enterprise Storage Platform, ESP).

UPSTREAM Reservoir is designed for those users who wish to take advantage of the many strengths provided by FDR/UPSTREAM, but would prefer to use an Open Systems storage server environment (e.g. Windows, AIX, Linux) for hosting the backup management engine.

PRODUCT OVERVIEW 1PART1.0 Introducing UPSTREAM

UPSTREAM is a powerful, reliable and high-performance suite of products for the data protection of Open Systems data. Your UPSTREAM system can be hosted on either:

• Az/OSmainframewithFDR/UPSTREAM (described here in this Concepts Guide).

• AnopensystemsserversuchasWindows,UNIXorLinuxwithUPSTREAM Reservoir(see inside back cover for details).

Whether it is just a few servers that you wish to back up, or your entire Open Systems infrastructure, the UPSTREAM suite offers a reliable, flexible and scalable solution to meet your requirements.

Regardless of where you locate your UPSTREAM storage servers, all backup and restore operations can be controlled and monitored through a common user interface, known as the “Director”.

Your UPSTREAM storage servers can be fully integrated with the systems and infrastructure inplace on the hosting system, allowing UPSTREAM to interact with key management systems, such as security, scheduling and tape management.

UPSTREAM’s high-performance backups can be optionally compressed and/or encrypted, and they can be directed to be stored on either disk or tape.

UPSTREAM is priced very competitively based on the number of TB being protected and currently includes extensive client and database support, plus many features that are often found as “cost options” in competing products, such as Archiving/Migration and File Transfer.

1.1 FDR/UPSTREAMFDR/UPSTREAM’s backup management engine, sometimes referred to as the “Storage Server” is located on a z/OS mainframe. It uses your existing z/OS infrastructure to provide a single, centralized point of control for all your Open Systems backups:

• It utilizes your z/OS system’s high-quality, robust disk/tape media for its backups, whichcan be stored in a compressed format for optimum efficiency.

• It makes full use of your existing, tried-and-tested z/OS system services, such as the TapeManagement System, Job Scheduling System and Security System.

FDR/UPSTREAM provides a flexible and scalable solution for securing anything from large corporate data servers, to smaller file servers or end-user workstations. It offers extensive client platform support, as well as intelligent agents for most of today’s most popular business applications.

1.2 Platform SupportThe data to be backed up by FDR/UPSTREAM can reside on any of the following server or workstation “client” platforms:

• Microsoft Windows • IBM AIX RS/6000 • VMware

• Novell NetWare OES2 • HP-UX • Sun x86

• x86 Linux • Sun Solaris • IBM z/OS UNIX

1.4 High-Speed BackupFDR/UPSTREAM offers several options for a high-speed and fl exible backup of your open systems data. These backups, which can be taken at either a Volume level or an Incremental File level, are directed to your z/OS storage server for safe, reliable storage and retention.

FDR/UPSTREAM has been designed to backup your open systems data as quickly and effi ciently as possible. It offers several choices for the transmission of backup data to the z/OS host:

• It can use high-performance network connections, such as 10GB Ethernet, or FICONchannel connections.

• For users looking to backup Linux for System z, FDR/UPSTREAM is also positioned toutilize Hipersocket connections (if available and confi gured on your z/OS host).

As well as using the fastest possible connections between the Open Systems client and the z/OS host, FDR/UPSTREAM also reduces to a minimum the amount of data that has to be transmitted:

• Its incremental backup scheme ensures that only the changed fi les are transmitted to thez/OS host–drastically reducing the time and resources required to take daily backups.

• The synthetic merge backup facility reduces the time required to take full backups, by merging the backups of changed data with backups of unchanged data already stored on the z/OS host.

• Duplicate fi le support avoids backing up fi les that are duplicated across multiple servers or workstations, saving on transmission time during the backups and also reducing host storage requirements. A single copy of each duplicated fi le can be stored in a central repository at the z/OS host.

• Segmented backup support is a form of Block level de-duplication, allowing you to take advantage of the phenomenon that most changes to large fi les and databases are typically made to a very limited percentage of the data. The fact that so much data does not change,means that much of the data in a large fi le does not have to be transmitted to be availablefor restore. Employing the same virtualization technique as full merge backup,i.e. copying data forward from prior backups and recovering data from incrementals, you can signifi cantly reduce transmission time and backup storage requirements.

• Optional compression further reduces backup times. Multiple levels of compression are available, all performed on the client prior to the data being transmitted to the z/OS host.

• A physical, byte-by-byte backup facility is also provided, which eliminates head or rotational delays when reading data from disk, and signifi cantly improves backup performance. Physical backups are of most use during disaster recovery.

• Users of EMC’s Symmetrix/DMX with z/SOS/VMAX and IBM DS8700 and DS8800 with zDDB DASD Subsystems can take advantage of FDRSOS and FDR/UPSTREAM/SOS, which are two separately priced products from Compuware. They work in conjunction with the EMC and IBM DASD array’s to provide high speed operations for Open Systems volumes across FICON channel connections. For more information, see the “FDRSOS andFDR/UPSTREAM/SOS” Concepts & Facilities Guide.

1.5 Fast, Flexible RestoresFDR/UPSTREAM offers great flexibility on restore operations. Individual files, groups of files, directories, drives and even whole disks or entire servers can be restored with just a few simple clicks. In addition, FDR/UPSTREAM also offers several useful features at restore time:

• Tape Vaulting. FDR/UPSTREAM allows you to create secondary “vault” copies ofsome/all of your backups, which can be placed offsite for safe storage. If the primarycopy of your backup is unavailable (e.g. after a disaster), a simple process enablesthe vault copies to be used for subsequent restores.

• Stand-Alone Recovery (SAR). This is a powerful feature of FDR/UPSTREAM whereyou can use a Windows machine with a SCSI-attached tape drive to perform disasterrecovery restores without requiring the z/OS host.

• The Rescuer. A powerful addition to the FDR/UPSTREAM storage managementsystem, which offers a complete backup and restore solution with disaster recoveryfor Linux for System z and UNIX. The FDR/UPSTREAM Rescuer is an enhancementto FDR/UPSTREAM that allows disaster recovery of select UNIX systems includingSystem z Linux, Intel Linux, and Solaris.The Rescuer provides this essential systemrecovery supplement because it is completely integrated into FDR/UPSTREAM.

1.6 Simplify, Centralize, Automate...FDR/UPSTREAM enables the effective protection of your business-critical open systems data by providing reliable and verifiable operations and simplifying, centralizing and automating your backup and recovery operations. FDR/UPSTREAM is designed to:

• Lower the cost of protecting your corporate-critical Open Systems data.

• Provide superior levels of protection for that data.

• Make efficient use of your tape media.

• Improve backup and restore capabilities.

1.7 The “Director”FDR/UPSTREAM includes a management interface called the “Director”, which offers the Systems Administrator a single, centralized and system-wide point-of-control for all FDR/UPSTREAM operations. The Explorer like interface, that can also be run from a Web browser, has multiple uses including:

• System monitoring, performance and management control functions.

• Ad-hoc or scheduled initiation of FDR/UPSTREAM backup/restore tasks.

• Extensive reporting.

• Non-Upstream job/task initiation.

• Host reporting facility (see PART FIVE).

1PART1.8 Exchanging Tapes with UPSTREAM ReservoirFDR/UPSTREAM is a member of the UPSTREAM family of products, which also includes UPSTREAM Reservoir, a backup/restore system similar to FDR/UPSTREAM, but hosted on an Open Systems server such as Windows, UNIX or Linux, rather than z/OS. See the “UPSTREAM Reservoir” Concepts and Facilities Guide for more information.

FDR/UPSTREAM and UPSTREAM Reservoir can both use a single, compatible tape format, which allows the interchange of backup data between the two systems. If required, backup tapes that are generated with FDR/UPSTREAM can be logically interchanged with UPSTREAM Reservoir and vice versa, assuming that the media is compatible.

So, for example, if you have 3590 tape drives on your Open System and on your z/OS system, UPSTREAM can read a tape-set created by either system, on either platform.

1.9 Additional FunctionsIn addition to the primary functions of backup, restore, and disaster recovery, FDR/UPSTREAM includes several other ancillary services:

• File Transfer. FDR/UPSTREAM can be used to transfer files from the client to the z/OS host, or vice versa. No additional software or communication connection is required. Text files may be translated between ASCII on the client and EBCDIC on the z/OS host. The transfers can be requested by either the z/OS host or by the client.

• File Migration. This is the process of taking a backup and then deleting files that are no longer required, or which have not been used for a period of time. With FDR/UPSTREAM, files may be migrated as part of the normal backup process, or the migration can be done separately.

• Data sharing/distribution. When backup copies of your data are stored in a location common to all users (i.e. the z/OS host), other users can easily retrieve that data–subject, of course, to security restrictions. FDR/UPSTREAM’s fast, secure and unattended nature makes it ideal for software sharing and distribution.

PART TWOSystem OverviewThis section provides an overview

of the main system components

of FDR/UPSTREAM.

It also describes FDR/UPSTREAM’s

additional support for Linux for

System z and IBM z/OS UNIX (USS).

1515

1PART2.0 IntroductionFDR/UPSTREAM consists of the following key components:

• The Storage Server

• The Client software

• The Director

This section takes a closer look at each of these components.

1. The Storage Server

The FDR/UPSTREAM Storage Server is located on a z/OS mainframe and is the main “engine” of FDR/UPSTREAM.

It runs as a standard z/OS started task with multiple sub-tasks and is responsible for the storage, retention and management of all FDR/UPSTREAM backups. It is also where the main configuration control files reside, together with the FDR/UPSTREAM database, which tracks the location of all current backups. Various log and history files are also maintained here.

The FDR/UPSTREAM host can be controlled by normal z/OS operator commands and also includes a full set of ISPF panels, which provide status monitoring and batch initiation services.

2. The Client Software

The data that you actually wish to backup with FDR/UPSTREAM can come from any server or workstation that can communicate with the Storage Server.

The FDR/UPSTREAM client software is installed on the server or workstation to be backed up and is responsible for accessing the files and databases during the backup and restore process. Data is transferred between FDR/UPSTREAM’s client and the z/OS host across one or more connections.

FDR/UPSTREAM uses TCP/IP as its internal communications protocol. No additional hardware or software is required for the two components to be able to communicate.

1PART3. The Director

In many organizations, often due to tactical and/or physical considerations, increasing amounts of corporate critical data are now being stored and maintained across a range of hardware platforms. As well as supporting these various platforms, FDR/UPSTREAM also offers the System Administrator(s) a single, system-wide point of control for monitoring all of its backup/restore activity.

The Director is a Graphical User Interface that can be installed and accessed from PC or workstation on the network. In most implementations of FDR/UPSTREAM, the Director is used by administrators as a “dash board” to monitor and control all aspects of the system.

As an example, here is a screen from the Director showing the status of a backup job running on a client elsewhere on the network. The backup is currently 31% complete.

The Director has multiple uses, including:

• A single, system-wide interface for the control and operation of all FDR/UPSTREAM operations.

• Ad-hoc or scheduled initiation/control of FDR/UPSTREAM backup/restore tasks.

• System monitoring, performance and management control functions.

• System Status.

The Director can also run in a web browser, such a Microsoft’s Internet Explorer or Mozilla’s Firefox, which essentially provides a ubiquitous web access to FDR/UPSTREAM.

T 22.1 System Summary DiagramThe following diagram illustrates the 3 main components of FDR/UPSTREAM.

Notice how the Director can be accessed from anywhere out on the network and how it can be used to control and/or monitor FDR/UPSTREAM operations (e.g. backups, restores, etc) that are running on other servers and workstations in the network.

Even if the Director is used to initiate a backup or restore task, the client machine still carries out the main communication with the FDR/UPSTREAM z/OS host in order to run the requested backup or restore task and to transfer the required data to/from tape.

1PART2.2 FDR/UPSTREAM For Linux on System z and IBM z/OS UNIXCorporations today are looking to leverage the strengths of the zENTERPRISE mainframes, for uses such as e-business applications and Web serving. With this in mind, FDR/UPSTREAM’s support for UNIX includes Linux on System z and IBM z/OS UNIX.

This support encompasses most of the facilities available for other UNIX platforms. For Linux on System z and IBM z/OS UNIX, this includes a full-featured daemon, together with a choice of command line, client character mode and Director user interfaces. The full range of FDR/UPSTREAM’s standard Storage Management features, as described in PART 1, is available under both platforms. The diagram below shows how FDR/UPSTREAM operates in conjunction with IBM z/OS UNIX (which operates within a z/OS LPAR) and Linux on System z (which operates as a separate LPAR on the z/OS host). Because the Linux on System z and IBM z/OS UNIX systems are resident on the z/OS host, the data transfer between the Client software and the host data storage software differs from the “standard” (i.e. network-based) operations described a moment ago.

As you can see, with the IBM z/OS UNIX system running on the z/OS Host #1, data can be transferred directly between the two FDR/UPSTREAM components (via TCP/IP) without going across a network connection.

And in the case Linux on System z, running on z/OS Host #2, the data is routed between LPARs across an Open Systems Adapter (OSA), so that the recipient (i.e. z/OS) is in the same box and routes the data straight there. Data transfer between the two FDR/UPSTREAM components can also be achieved utilizing a feature called “TCP/IP Hipersockets”, that is available for the z/OS operating system to add function for Linux on System z.

With Hipersockets, the TCP/IP data can be routed directly between partitions in a z/OS machine, without going to the OSA and bouncing off. The utilization of Hipersockets is transparent to applications like FDR/UPSTREAM, which just do their normal TCP/IP calls. However, because the data transfer does not involve the OSA, it is significantly faster.

PART THREEThe Backup/Restore ProcessesThis section describes

FDR/UPSTREAM’s primary

functions of backup and restore,

as well as Disaster Recovery issues.

It looks in more detail at the

various features within

FDR/UPSTREAM to maximize

backup and restore performance.

2020

1PARTPART 33.0 The FDR/UPSTREAM Backup SchemeFDR/UPSTREAM’s flexible backup scheme can be used to secure everything from a whole server or application down to individual folders or files. In general, FDR/UPSTREAM backups are usually created to secure either a single or group of volumes in a server, or all the folders relating to one or more applications on the server. These backups are then run at either:

•A “full ” volume level, where all files in the file specification get backed up.

• An “incremental ” level, where only the changed or modified files are backed up.

For Windows systems during the Incremental process, FDR/UPSTREAM checks the archive bit and backs up only the changed files—drastically reducing the time required to take daily backups. In UNIX systems, where no archive bit is maintained, (and optionally for Windows), there is an option for FDR/UPSTREAM to use its own “local incremental database” to record the files it has backed up, and thus determine which files are to be included in the next incremental backup.

Failed backups (i.e. due to communications failure, host unavailability, etc) can be restarted at the point of failure.

Below you can see two example screens from The Director, which is being used to define an FDR/UPSTREAM backup task.

On the left-hand screen we have selected various volumes to be backed up. (Note: If the whole server needed to be backed up, this could be done with a simple “ \\.” selection without needing to specify each drive individually). As well as the full C:, F: and H: drives, we have also selected the “Backups” and “Utility” folders from the G: drive. Notice also that we have some excludes for various folders that we don’t want to back up from the previously selected C, F and H drives.

On the right-hand screen we are setting options to control various aspects of the backup, such as “tape usage” and “backup retention” settings.

BACKUP/RESTORE PROCESSES

2121

1PARTPART 33.1 Backup ProfilesIn order to associate a series of backups with a server, one or more unique backup “profiles” are defined within FDR/UPSTREAM for each server (or collection of files) that it will backup. These profiles provide the user with an easy way to name and identify individual server backups for recovery and reporting purposes.

The information provided in each backup profile includes tape handling characteristics and backup retention requirements.

3.2 Backup File ManagementAs described earlier, the z/OS host component of FDR/UPSTREAM stores, records, maintains and expires the backups.

• FDR/UPSTREAM backups can go to either z/OS disk; physical or virtual tape.

• All backups are cataloged in a standard ICF user catalog.

• The retention/expiration of these backups can be controlled by either RETPD/EXPDT, or by z/OS GDG roll-off processing.

• Backup files on disk can be controlled by DFSMS and can be directed to the appropriate Storage Group, as selected by the ACS routines. Alternatively, they can be allocated to specific disks, as determined by parameters set in the FDR/UPSTREAM configuration.

• Backup files on tape can be controlled by the z/OS Tape Management System (if present), which will direct them to an appropriate tape and record all of the required information. The Tape Management System can also control offsite vaulting of these tapes, if required.

• Authorization for the allocation and usage of all FDR/UPSTREAM backup files can be controlled by your z/OS Security System.

As well as interacting with various components of the z/OS host operating system, FDR/UPSTREAM also has several of its own internal facilities that help with the management and control of your backups:

• Additional copies of backups can be created for off-site storage, or for long-term archival of data.

• Backup files can be migrated onto tape via the vaulting utility. The FDR/UPSTREAM database will be updated to reflect the new location of the backups. Backups from more than one server can be optionally consolidated (stacked) onto a single tape or tape set (see PART FIVE).


2222

1PARTPART 33.3 Backup PerformanceAside from the elapsed time savings provided by features already described, such as the incremental backup process, FDR/UPSTREAM also offers several other data reduction and performance features.

The following features aim to minimize the amount of data that is transmitted from the client component to the z/OS host, while at the same time offering low resource usage and system utilization:

• Data availability

• Data compression

• Synthetic Full merge backups

• Deferred Merge

• Segmented Backup support

• Intelligent database agents (see PART FOUR)

Let’s take a closer look at each of these features.

Data Availability

FDR/UPSTREAM is well suited to take advantage of the features that Storage Array vendors provide for high-speed and flexibility of modern SAN environments. The list includes IBM FlashCopy, EMC TimeFinder, Hitachi ShadowImage, and SUN StorageTek SnapShot Copy.

These disk “shadowing” or “replication” technologies enhance server availability by providing a fast, point-in-time copy of a standard source volume. After the replicated copy of a volume has been created, it can be backed up while the source volume is in use. While FDR/UPSTREAM supports these technologies and their usage can be automated, they do introduce a level of complexity to the backup process.

FDR/UPSTREAM also supports the Volume Shadow Copy Service (VSS), available under the Microsoft Windows operating system.

1PARTPART 3Data Compression

The elapsed times of FDR/UPSTREAM’s Full and Incremental backups can often be drastically reduced by using the optional data compression feature, whereby the backup data is compressed on the client machine prior to its transmission across to the z/OS host. This means that client data is backed up and stored in a compressed format.

Multiple levels of data compression are available to help balance the cost in terms of time and resources used to do the compression against the end result of the reduced transmission times.

Full Merge Backups

Many backup Administrators find it beneficial to intersperse daily incremental backups with a periodic full backup, where every file is backed up irrespective of whether it has changed or not. However, because of the potentially large volume of data, these full backups can consume client-side resources and impose uncomfortable loads on the network.

FDR/UPSTREAM’s efficient full merge backup mechanism allows administrators to obtain the benefits of the full backup, without these overheads, by combining backups on the host.

To create a full backup, the Full Merge Backup mechanism backs up only the changed files from the server. What makes this backup different from a normal incremental backup is that it also sends a copy of the directory entries of the unchanged files to the host. Then, instead of using network and client-side resources to transmit these unchanged files to the host, FDR/UPSTREAM simply retrieves the most recent copy of each file from the prior backups.

Using CPU resources only at the host end of the operation, FDR/UPSTREAM then combines all of the transmitted files, together with the retrieved copies of the unchanged files, to create a new merged Full Backup, which contains an up-to-date copy of every file. A full backup has thus been created using client-side resources that are only marginally greater than on a standard daily incremental backup. The following diagram summarizes this process:

So, in summary, the FDR/UPSTREAM full merge process eliminates the need to do any regular (i.e. weekly) full backups. After your initial first-time full backup of your data, you only ever take Incremental and periodic full merge backups, saving both time and resources.

An efficient and periodic full merge backup also helps to reduce the number of backup tapes that need to be loaded during a recovery process, which in turn can help to shorten the recovery time.


2424

1PARTPART 3Deferred Merge

While the UPSTREAM Synthetic Full Merge backup is the most efficient and effective type of full backup that you can take, it does require that the client system is connected and remain communicating to the UPSTREAM Storage server transmitting data for the duration of the entire operation. For large amounts of data this can result in long wall clock time. The UPSTREAM Deferred Merge backup circumvents and overcomes this issue by completing the backup portion of the operation significantly quicker and delays the portion that does consolidation and collocation of prior backups to a later time.

With this method the UPSTREAM Deferred Merge provide 2 types of Data De-Duplication:

1. A way to think about Data De-Duplication is by where it occurs. When the de-duplication occurs close to where data is created, it is often referred to as “source de-duplication.”

2. When the de-duplication occurs near where the data is stored, it is commonly called “target de-duplication.”

The Deferred Merge uses Source side target de-duplication by not sending files that haven’t changed…already have a copy of the files.

• Therefore you are not using network bandwidth for unchanged files

• Backup wall clock time is shorter so you can make your backup window

• And you are not using unnecessary tape or disk resources or drive hours

• And your data is always fully protected

The Deferred Merge when selectively storing only changed files is using “target de-duplication.”

• You are able to restore ANY file from anything that is retained

• With benefits of significant reduction of back end storage, network bandwidth, and CPU utilization

• And your data is always fully protected

The UPSTREAM Deferred Merge is superior to products that do incrementals forever as large recoveries are significantly less resource intensive.

1PARTPART 33.4 The Restore Process The restore capabilities of FDR/UPSTREAM are as powerful, flexible and reliable as the backup processes described earlier.

• When required, individual files and/or directories can be restored.

• In the event of a disaster, whole servers and workstations can be recreated.

Using the Director or ISPF interface, FDR/UPSTREAM can display all files in a given directory for a single backup, or intelligently combine Incrementals and the Full backup into a single consolidated view. It is also possible to view all backup versions of a file that are currently being maintained by FDR/UPSTREAM.

Having displayed the various backups for files, directories and subdirectories, the required versions can then be selected for restore, either to their original location, or a new location. Multiple selections can be made, and options are provided to prevent files from being restored if a copy already exists on the receiving disk.

As FDR/UPSTREAM has recorded the details of where on the z/OS the backup is located, the administrator or end-user doing the restore does not have to tell it which tape(s) to mount, or which disk(s) the backup was written to.

Here is an example of The Director interface being used to restore several files from a folder called FDRCRYPT Results.

3.5 Disaster RecoveryFDR/UPSTREAM provides comprehensive data protection for enterprise servers that includes file level data protection support and also “Bare Metal” system recovery.

Disasters can come in many forms and can happen at any time. Hardware failure, server crashes, data corruption, electrical problems and even human error can all result in the same situation having to perform an Operating System installation and configuration and then restore your data. In the event of such a disaster, i.e. where complete servers/workstations need to be restored, FDR/UPSTREAM offers several facilities for the reconstruction and restoration of your data:

• It can use the powerful combination of the weekly Full-Merge backups, together with the daily Incrementals to provide a complete “Back-to-Full” recovery of drives, folders or even entire applications. The start point of the recovery process can be controlled so that the data can be restored back to the point of any given backup

• FDR/UPSTREAM also includes its own specially formulated procedures for the recovery of server and/or workstation operating systems, including Windows, NetWare, UNIX and Linux. These procedures often require just a basic pre-installation of the base Operating System, with FDR/UPSTREAM then restoring the site-specific configuration files etc.

• FDR/UPSTREAM now provides an enhanced Bare Metal Recovery for Windows Server 2008 64 bit systems and above. The process of the Bare Metal Recovery promotes automation, consistency, and reliable operations to the server recovery process. The enhanced recovery eliminates the need of reinstalling the operating systems or manually configuring hardware making server recovery simple and can be performed in a fraction of the time.

• If you are recovering an older Windows system, you can also use FDR/UPSTREAM’s legacy existing System Recovery facility, that combines the recovery of the operating system with the recovery of application data.

3.6 The RescuerFDR/UPSTREAM Rescuer allows disaster recovery of select UNIX systems including Linux on System z, Intel Linux, and Solaris. A recovery with the Rescuer requires an initial full FDR/UPSTREAM backup of the system, which may optionally then be followed by subsequent incremental backups. FDR/UPSTREAM backups include all of the information necessary for a full system recovery, including device files, FIFOs, hard and symbolic links and more.

The Rescuer uses the single user or emergency boot facilities provided by the UNIX or Linux vendor. Then, with the operating system loaded and running, the disk to be recovered is created and mounted and the restore done, avoiding potentially fatal problems of overwriting the active operating system disk.

The new Enhanced FDR/UPSTREAM Linux on System z Rescuer provides the ability to recover the Linux Virtual Machine in a single command. FDR/UPSTREAM does not backup partition or other disk definition information. However, on all Rescuer systems, a disaster recovery report is created which can be either backed up or sent via an email notification (see “Notification Facility” in PART FIVE) to make the information available at disaster recovery time.

Note: The methods and procedures for these recoveries differ across operating systems, so please see the FDR/UPSTREAM user documentation for full details.

the support provided in

FDR/UPSTREAM

for today’s most popular

databases, messaging systems

and groupware applications.

PA

RT 4 DATABASE SUPPORT

4.0 IntroductionToday’s databases and messaging systems are generally regarded as “business-critical”, and the need for an effective backup and recovery solution for these systems has become apparent for most companies. Keeping these applications online, in production and aligned to 24x7 operations helps the organization’s bottom line. Not having to shutdown a critical database or messaging system to perform backups is now a necessity rather than a luxury.

FDR/UPSTREAM’s range of database agents offers the ability to take non-disruptive, full and incremental “hot backups” of most of the popular database/messaging systems in use today. An option is also provided to execute scripts with pre- and post-backup conditional processing (see below), providing a totally automated solution for high-quality backups in a 24x7 environment.

4.1 Database SupportFDR/UPSTREAM includes specially developed agents to provide online hot backup facilities for the following popular database, messaging and groupware systems:

• Oracle

• IBM DB2 UDB (Universal Database Server)

• IBM Notes and Domino

• Microsoft Exchange

• Microsoft SQL Server

• SAP

4.2 Pre- and Post-Backup Conditional ProcessingThe Pre- and Post-Backup conditional processing facilities within FDR/UPSTREAM allow the administrator to prepare a database system for backup (or restore). As an example, this might involve running a SQL script or doing work with transaction logs.

An FDR/UPSTREAM “job” would be started on the Storage Server, which then contacts the UPSTREAM client software running on the server or workstation to be backed up, telling it to execute the pre-process batch file, program, or script. Once that process has completed successfully, the actual backup of the database can take place. When the backup is completed, a post-processing facility could then also be automatically executed if required.

Should the pre-process job fail for any reason, the UPSTREAM function itself would not be performed and would return a non-zero return code to the Storage Server. Any post-processing would also be suspended. This is just an example of the coordinated and cohesive support that FDR/UPSTREAM can provide for large database applications to reduce the workload of the DBA and Storage Administrator. The result is a totally automated method for safely and securely backing up your databases while providing useful feedback about the success or failure of the operation.

This section now looks in more detail at the support offered by FDR/UPSTREAM for the most popular database and messaging systems in use today.

4.3 OracleFDR/UPSTREAM offers several methods to backup Oracle databases, while at the same time reducing system downtime. A variety of backup techniques are available, including:

• File level backup

• Logical volume backup

• RMAN support

As well as providing backup services for your Oracle databases, FDR/UPSTREAM can also be used to backup the Oracle system itself, allowing a complete protection of your overall Oracle environment. Innovation’s membership in Oracle’s Backup Solution Provider (BSP) program allows FDR/UPSTREAM to operate as an Oracle Media Manager Library product and to use the power of Oracle Recovery Manager (RMAN). RMAN is a full-featured backup facility that can be used with FDR/UPSTREAM to perform online and offline, full, incremental and tablespace backups of databases, tablespaces and data files.

All of the powerful features of RMAN are available to FDR/UPSTREAM users under both local and host control.

Multi-Channel SupportFDR/UPSTREAM support for Oracle databases also includes multi-channel support for multiple simultaneous backups and restores. With this feature, FDR/UPSTREAM will transparently manage the parallel backups by internally splitting the backup process into separate backup streams. This powerful feature, which requires no administrator intervention, significantly reduces the runtime for backups and restores.

See the Oracle section of the UPSTREAM Client User Guide for more details.

PA


4.4 DB2 Universal DatabaseFDR/UPSTREAM support for IBM’s DB2 Universal Server (UDB) provides a backup agent that includes support for Windows, AIX, HP-UX, Solaris, Linux and Linux on System z systems. The agent features include:

• Full, partial and incremental backups as available in the DB2 BACKUP commands as a “vendor DLL”.

• Online and offline support, with full and incremental backup

• Tablespace level backups and restores

• Support for transaction log backups using the vendor DLL or user exit

• Point-in-time capable roll-forward restores

• Flexible scheduling from either the host or client scheduler

• Interaction with DB2 scripts for seamless operation and reduced training costs

• Support for DB2 “load utility”

• Automatic notification of agent failure

• Archive and auto-recall of transaction logs

• Database and transaction log aging controlled from within DB2

See the DB2 section of the UPSTREAM Client User Guide for more details.

4.5 IBM Notes and DominoThrough the IBM Notes API (for Windows, AIX, Solaris, x86 Linux, Linux on System z and IBM z/OS UNIX), FDR/UPSTREAM provides a robust, integrated solution for the protection of critical Notes and Domino information, enabling online backups of IBM Notes and Domino without disrupting user productivity. FDR/UPSTREAM can also be used to backup and recover the Notes application itself.

FDR/UPSTREAM can perform online full backups of Notes databases (even if they are in-use) as well as incremental backups, by backing up Notes transaction logs—which is essential if you are using transaction logging. FDR/UPSTREAM will recognize if a new database has been added, and it will back it up even if you are performing incremental backup. To add a further performance edge, FDR/UPSTREAM can also perform multiple simultaneous backup operations. The FDR/UPSTREAM support for IBM Notes is extensive and includes:

• Full backup of online databases (.nsf) and templates (.ntf)

• Automatic backup of important non-database data (e.g. Notes ID files and ‘.ini’ files)

• Automatic expiration of database backups based on version limit and retention period. The restore capabilities are equally impressive:

• You can restore a database to a specific point-in-time, or to another IBM Notes server

• You can apply changes to a restored database (from transaction logs)

• You can restore individually active and archived transaction logs

• FDR/UPSTREAM can also be used to recover a Notes database in a disaster recovery situation.

3131

If required, all FDR/UPSTREAM operations can be scheduled using the Domino Scheduler in preference to the scheduling facilities provided by FDR/UPSTREAM or by the client operating system. FDR/UPSTREAM also provides a command line option, which allows you to migrate old Notes. This can be useful, for example, in generically migrating old email messages to a separate Notes database, which can then in turn be migrated using FDR/UPSTREAM migration.

4.6 Microsoft ExchangeUPSTREAM provides full support for Microsoft Exchange 2007, 2010 and 2013. The FDR/UPSTREAM agent provides full and incremental backups and transaction log backups.

See the Exchange section of the UPSTREAM Client User Guide for more details.

4.7 Microsoft SQL Server Microsoft SQL Server provides a number of backup and restore options that provide DBAs with the flexibility they need to plan their database recovery strategy. Using a Microsoft API, FDR/UPSTREAM can take advantage of these options to aid in the automation of SQL backups and restores. FDR/UPSTREAM provides a backup agent which offers online, full and transaction log backups of SQL databases.

See the SQL Server section of the UPSTREAM Client User Guide for more details.

4.8 SAPFDR/UPSTREAM includes an agent for backing up Oracle-based SAP R/3 databases. Platforms supported include Windows, AIX, Solaris and HP-UX. Backups and restores are requested and initiated using SAP utilities (sapdba, brbackup, brarchive, etc.) which drive the FDR/UPSTREAM backup agent to perform the requested function.

RT 5 ADDITIONAL FEATURES

5.0 IntroductionAside from the primary functions of Backup and Restore, FDR/UPSTREAM also includes various utility functions and other useful features. This final section describes those features in more detail.

5.1 Vaulting and Migrating Your BackupsFDR/UPSTREAM allows you to copy, vault, consolidate and move your backups. You might want to use these facilities when:

• With Vaulting you can make additional copies of one or more backups for extra security. These are a true copy of the original backup, but they are not recorded separately in the FDR/UPSTREAM database (although the database records can be updated to point to the copied backups, if required).

• You wish to make additional vaulted copies of your backups, usually for the purposes of offsite storage and disaster recovery.

• You wish to migrate onto a single tape a selection of backups that are currently spread over many tapes (or disk files). This would be done to optimize tape utilization.

• You wish to migrate one or more disk-based backups to tape.

The following diagram illustrates these very useful FDR/UPSTREAM utility operations:

5.2 ReportingFDR/UPSTREAM includes various “log” files containing either detailed or summary information. These files can be browsed and reported on by FDR/UPSTREAM Systems Administrators for general reporting/feedback purposes, as well as being a vital source of information for problem determination. The USTRPORT “BACKUP” report can display information about servers being protected. Additionally, available as a z/OS batch job, output can also be made to a CSV file.

5.3 Host Reporting with the DirectorHost Reports can also be produced from the Director interface. These reports can use a variety of different data sources and can be displayed either to a new window in the Director, or written to a flat file. In the sample screen below we are requesting a report of all backups with a backup profile of XPRES with a condition code of “Failed”.

The resultant report from that report request would look something like this when displayed as a new window in the Director:

3737

PA


5.4 Notification FacilityThe Notification facility further assists the Storage Administrator with the automation and control of FDR/UPSTREAM operations. It allows backups and restores (and any other FDR/UPSTREAM-initiated task) to send an E-mail notification or SNMP traps to interested parties of a successful (or, if required, an unsuccessful) completion of the task. This feature adds yet another valuable layer of automation to your Storage Management operations and strategy.

5.5 Registered NamesThe “registered name” facility further eases the System Administration effort by allowing the assignment of a logical name to a client machine, rather than the actual IP address and TCP Port Number of the target machine to be backed up. This makes the FDR/UPSTREAM backup operation independent of the actual network address and also allows these values to dynamically change, which is very useful when roaming clients are connecting to the network using DHCP or a similar scheme.

5.6 ISPF PanelsAs an alternative to the client-side GUI panels and the Director Java Interface that were described in PART 1, FDR/UPSTREAM also includes a complete set of TSO ISPF panels which, among other things, can be used to create and manually initiate backups and restores. The backup/restore specifications are saved as JCL, which can then be submitted as standard z/OS batch jobs, optionally through the z/OS job scheduler.

Here is the Primary Option panel showing the menu of options that can be controlled through ISPF:

3838

PA


And here is an example of just one of the many panels that are useful to the UPSTREAM Administrator. This one shows the “Registered Names” facility. Rather than using the TCP/IP addresses to locate backup/restore targets, the UPSTREAM administrator has allocated meaningful names, such as “ADMIN5” and “BOBXP”. Notice also that the screen shows the current version of the UPSTREAM client software being run on each machine.

5.7 SummaryFDR/UPSTREAM is the ideal tool for taking reliable and high-performance backups of yourOpen Systems data. In summary, it provides:

In addition, FDR/UPSTREAM also includes important reporting/feedback facilities to ensure that you always know what backups you’ve taken and where those backups are stored. And, most important of all, FDR/UPSTREAM provides flexible and reliable Restore and Disaster Recovery procedures to ensure that, in the event of any problems, you can get your data back...whenever and wherever you need it.
