BACKUP SOFTWARE
What is it?
• Software that provides automated data protection for businesses with 24x7 availability needs.
What does it do?
• Data Protection: copies data onto a storage device, so that in case of a need (loss, corruption, disaster), data can be easily recovered and made accessible.
• Media management: easily manages the library catalogues to keep track of all media and copies of data for fast recovery.
Most important features:
• Automated backups that scale from small workgroups to multi-site, heterogeneous SAN & NAS environments with thousands of servers.
• Fully-integrated Zero-Downtime backup with Instant-Recovery.

• Consolidation is required
• Multiple servers are configured together
• Unattended backup
• LAN or SAN based backup
• Disk capacity to be backed up is more than 1 TB
• Consolidation and centralized management is required
• Storage external to servers in JBOD or disk arrays

Features Required in any Backup software• Advanced backup to disk
• Oracle/SAP Integrations
• Zero Downtime Backup
• Split mirror

Overview – Advanced backup to disk
Why backup to disk?Benefits
• Fast random access allowing:– Fast single file restore– Space efficient backup
• Instant recovery– e.g. switching for recovery instead of restoring
data from tape• Faster restore of backup chains• No tape streaming problems• Ideal for RAID 5• Easy to detect disk failures• More protected, e.g. it’s not easy to steal a disk
![Page 28: Storage Overview And Architecture Arvind Shrivastava](https://reader036.vdocument.in/reader036/viewer/2022062421/56649d035503460f949d6eb4/html5/thumbnails/28.jpg)
Advantages of ZDB
The advantages of using Data Protector Oracle ZDB integration are the following:• ZDB reduces the performance degradation of the application system.• The tablespaces are in backup mode (online backup) or the database is shut down (offline backup) only during the short period required to create a replica (split the mirror disks or create snapshots).• The time to create a replica is significantly reduced. Following its creation, tape backup can be created on the copied data, at leisure , using a separate backup system.•The Data Protector Oracle ZDB integration offers online and offline backup of your Oracle Server System (application system).

Where is the Pain ?
Under-utilized assets
• Storage infrastructure
• IT staff
Cost of heterogeneous management is expensive and inefficient
Application down time issues angers the customer
• Troubleshooting is time consuming
• Help desks are flooded
Server consolidation/data center moves drives the budget
On-going justification of the budget
• What happened to all the storage?
• Why do we need more now? When again?

Key Qualification QuestionsIdentifying the Pain Points
How do you manage increasing storage capacity with flat or shrinking IT headcount?
Do you have a SAN? Can you tell what the impact of a lost SAN element will be on your applications and users?
How do you keep your staff trained on a wide range of device-specific element managers and tactical SRM tools that, right now, only add complexity?
Do you want to replace the whiteboards and spreadsheets you’re currently using for SAN management with something that is more scalable and reliable?
How do you avoid vendor lock-in and heavy, proprietary agents that come with other solutions?
Can you provision storage in real time to support new applications and projects?
How do you comply with SAN change control and internal audits?
