Figure 32 Using VLS in Larger VMWare Environments with HP Data Protector ZDB IR Backup
Recovery options:
Two step restore process that provides full recovery of VM and data
Recover the VM image from VCB backup
◦
◦
Required only in case the whole VM is lost or restore to a new ESX server
Recover Application Data
For replication-based disc backups (IR), perform Instant Recovery
◦
For disc/tape backups, restore directly to the VM
◦
◦
Recovery performed automatically by Data Protector as specified by user
Solution advantages:
VCB snapshot-based backup is not really "application aware" whereas HP Data Protector
ZDB quiesces the application prior to the hardware-based snapshot. It is much more suitable
for live databases and email servers than VCB-based backups.
Remove the backup load from VM to a backup server with Data Protector Zero Downtime
Backup
Reduce application recovery times from hours to minutes with Data Protector Instant Recovery
Easy copy to physical tape if required
Solution trade-offs:
Limited to EVA & XP & LHN (Future)
Snapshots could take up large amount of EVA and XP space depending on frequency of
snapshots- at extra cost
