Using Vls In Larger Vmware Environments With Hp Data Protector Zdb Ir Backup - HP StorageWorks 12000 - Virtual Library System EVA Gateway Manual

Figure 57 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
