Disaster recovery of ESX environments
Easy transfer to physical tape if required, if backup application used
With HP Data Protector and most other backup software the following approaches are possible:
• Online and offline snapshots of VMs. File level backup and recovery of data in the VMs.
• VCB Image Backup: Online and offline snapshots - full backup only.
• VCB File Backup: Full backup. Incremental and differential backups based on per-file modific-
ation time. Incremental contains changes since previous backup; differential contains changes
since latest full backup.
Solution trade-offs:
Full snapshot-based recovery – single file recovery only on Windows file system backups.
Distinctly separate proxy server required at additional cost – requires additional storage for copy
of snapshots.
Backup application integrations such as Oracle, SQL, Exchange, etc., cannot be used with VCB.
VLS cannot deduplicate NetBackup VCB with FlashBackup data type yet which is used for single
file restore from a VM image backup.
Other information: After snapshot has been copied to proxy and backed up , it is deleted from the
primary storage array where it was first taken.
Further enhancements possible by providing multi site disaster recovery by using low bandwidth
replication on HP VLS devices.
Larger VMWare Environment with ESX4 and HP Data Protector ZDB IR Integration with
VMWare Consolidated Backup
Company requirements: Large VMWare environment, high throughput required to meet backup
window (Fibre Channel). High SLAs require "Instant Recovery." Requirement for online application
backups using techniques such as HP Zero Downtime backup. Common backup solution required for
VMWare and other SAN host in the company's infrastructure. Room for growth, and more backup
data online (for SLA) dictates need for deduplication.
Solution: HP VLS9000 with deduplication plus HP Data Protector ZDB implementation for SQL,
Exchange and Oracle.
Caveats: Limited to arrays that support DP ZDB IR – XP, EVA and LHN (future).
ISVs: HP Data Protector and Symantec Netbackup only at this time fully tested by HP.
Device configuration highlights: Configure different virtual libraries for SQL, Exchange, Oracle snapshot
backups.
Backup application configuration highlights: Configuring Zero Downtime Backup within Data Protector
and Symantec Netbackup requires some additional scripting work. See the HP EBS SAN Design
Guide at http://www.hp.com/go/ebs.
