Large Enterprise Cross-Site Backup With Deduplication And Inbuilt Disaster Recovery - HP 12000 Design Manual

1. VM backup
Data Protector Integration with VMware VCB provides the first layer of protection
Provides snapshots that can be used for restoring VM
Needed only when VM configuration changes
2. Application backup
Provides the second layer that enables protection of application data
Can be performed using ZDB/IR feature of Data Protector by using HP Business Copy
for EVA, XP (LHN to follow)
Further enhancements possible by providing multi-site disaster recovery by using low bandwidth
replication on HP VLS devices.

Large Enterprise Cross-site Backup with Deduplication and Inbuilt Disaster Recovery

Company requirements: Fully redundant system with automated offsite backup over extended SAN
– getting data offsite immediately is the requirement. Manage data growth, keep more data online,
regular archiving to tape using object copy.
Solution: VLS9000 with deduplication over extended SAN. ESL library for high volume archiving.
Caveats: CWDM bandwidth is the critical performance factor in this solution typically using HP
Multi-Protocol Routers.
ISVs: HP Data Protector, Symantec Netbackup and TSM (deduplication support) only at this time.
Device configuration highlights: Normal VLS deduplication requirements – small cartridges, strict
backup policy naming.
Backup application configuration highlights: RMAN stream naming scripting required for best
Oracle deduplication performance.

Recovery options: Depending on retention time on the VLS, data can be recovered directly from
VLS on the remote site or if that retention has expired then a copy should be archived on physical
tape which is again directly available from the remote site over the extended SAN.
