Virtual Machine Backup Methods

• Image-level Backups – Capture entire snapshots of virtual machines

– Enables full virtual machine recovery and granular file/folder recovery

• Agent-assisted Backups (for virtualized applications) – A form of image-level backup

– Includes application recovery and granular application recovery support

– Requires AWS to be installed to virtual machine

• Agent-based Backups – Legacy backup method

– Backups are captured by a local agent installed to a virtual machine

– Recommended only in situations where image-level backups are not optimal, such as Physical Compatibility Mode RDM disk configurations



VMware Backup Transport Modes

• SAN

– Uses iSCSI or Fiber Channel shared storage for data transfers

• HOTADD

– Uses a virtualized Backup Exec server that exists as a virtual machine

• NBD

– Uses the LAN/Ethernet for data transfers

• NBDSSL

– Uses the encrypted LAN/Ethernet for data transfers



Virtual Disk Types

VMware Virtual Disk Types

• Both thick and thin virtual disks (VMDK) are supported

• During recovery, the administrator can select to restore as either a thick or thin virtual disk

Hyper-V Virtual Disk Types

• Both dynamically expanding and fixed size virtual disks (VHD) are supported

• When recovered, a virtual machine will have the same VHD type as it had when it was backed up

New! Backup and Convert to Virtual

Convert Stream

Convert to Virtual (P2V) – Parallel data streams

– One stream to media server

– Other stream to hypervisor

– Result is full virtual machine (not just the virtual disk)

Backup to Virtual (B2V) – Serial data streams – Backup stream to media

server – Conversion job runs after or

on different schedule – Result is full virtual machine

(not just the virtual disk)

Granular Recovery for Physical, Virtual Applications

Symantec V-Ray



Application Protection in a VMware Environment

• Image-level Backups Using Virtual Agent – Entire virtual machine, including any applications, protected via VSS

– Ensures applications are in a consistent state at the time of backup

– VMware tools must be installed to the virtual machine

– Recovery options limited to full virtual machine recovery and file/folder recovery

• Agent-assisted Backups Using Virtual Agent – Entire virtual machine, including any applications, protected via VSS

– Ensures applications are in a consistent state at the time of backup

– Backup Exec Agent for Windows Systems must be installed to the virtual machine

– Recovery options include:

• Full virtual machine recovery

• Application recovery*

• Granular application recovery*

• File folder recovery

* requires license of the Agent for Applications and Databases


Symantec V-Ray


Virtual Machine Recovery Options


• Multiple restore options:

• Entire VM

• Entire application/database

• Granular SQL, Exchange, SharePoint, or Active Directory data

• Individual files or folders

• From a fast, single-pass backup!

• Reduce storage requirements with Deduplication: BE 2012 reduces redundant data across multiple VMs and their VHD/VMDK files.

• Reduce backup impact on production VMs: Backup data captured from single backup (single-pass)

Virtual Disk

• Backup Exec 2012 automatically catalogs VMDK/VHD files during standard backup processing

Symantec V-Ray

Notes and Best Practices



VMware Best Practices

• Configuring SAN-based backups for VMware with Backup Exec 2012:

– Zone LUNs with VMFS data store so the Backup Exec server can access them.

– On Backup Exec server ensure “automount disable” and “automount scrub” commands have been run to disable automatic drive letter assignment.

– As a result, VMFS datastore LUN’s should appear in Windows Disk Administrator (on the Backup Exec server) as “unknown”; this is correct.

• Backup performance largely determined by the slowest component; these components are:

– vSphere server system resources: CPU (GHz)

– vSphere system disk I/O capabilities (Gbps)

– Network type (Fiber Channel 1/2/4/8GB, iSCSI, 1/10GB Ethernet, etc)

– Backup Exec server system resources




• Basic guidelines when configuring Backup Exec in a VMware environment:

– For SAN-based backups, consider installing Backup Exec on a physical machine.

– The internal bus of the Backup Exec server should be fast enough to support the I/O devices that are connected to it; if multiple I/O ports are used, a system with multiple internal buses should be considered.

– Backup Exec server I/O performance is generally more important than CPU performance.

• For more information, see Backup Exec Technote http://seer.entsupport.symantec.com/docs/346047.htm


http://seer.entsupport.symantec.com/docs/346047.htm



• Number of Virtual Machines to Protect with a Single Backup

Exec Server

– No limit to number of VMs that a single Backup Exec server can protect

– Highly dependent on the size of the VMDK files and backup infrastructure

– In large environments, multiple Backup Exec servers can be used to

optimize performance

• Backup Protection Recommendations

– Seven-day rotation with incremental and differential backups

• Full backup is run on the 7th day to avoid long incremental/differential backup chains.

– Use the Backup Exec 2012 Deduplication Option be used in conjunction

with the Virtual Agent



VMware Notes

• Some Features Require vSphere 4.x or 5.0

– Incremental and Differential backups require vSphere 4.x or later, HW version 7 or later

– Change Block Tracking required for incremental/differential backups

– BE 2012 Server is always the target for vStorage backups • No remote VCB Proxy Servers

• Staging Required for GRT Restores From Tape

– VMDKs are staged from tape back to temporary disk location before granular restore



VMware Notes

• RDM Physical Compatibility Mode Disks

– RDM (Raw Device Mapping) Physical Compatibility Mode disks bypass the ESX storage infrastructure

• GPT Disks

– Image-level backups are supported, including full, differential, and incremental backups

– Granular file and application recovery is not supported

• vSphere 4.0/5.0 Fault Tolerance

– Fault Tolerance disables snapshots; vStorage backups are snapshot-based

Workaround is to Protect VMs via Local Agent for Windows Servers
