Using D2D In Larger Vmware Environments With Hp Data Protector Zero Downtime Backup With Instant Recovery (Zdb + Ir) - HP StorageWorks 12000 - Virtual Library System EVA Gateway Manual

Recovery options: Recovery is a two stage recovery: 1) the image is restored to the VCB proxy or the
ESX server, and 2) the image is restored as a VM using VMware Converter if restored to the VCB
proxy, or vcbRestore if restored to the ESX server.
Restart the VM and you are back in business as of the last snap. This is the fastest way to do a complete
disaster recovery. For example HP DP on Proxy can restore directly from D2D/Tape onto VM machines.
For Windows OS, you can also mount the filesystem backup to VCB proxy and restore single files or
restore the complete system.
Solution advantages:
• VMWare approved method of backing up, takes the load off the ESX console for backup and
restore and passes it to the proxy server
• Allows all HP supported Fibre Channel backup devices to be connected to Proxy server
• VCB is disk array independent snapshot technology.
• Automation of backup and restore of VM snapshots.
• 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 modification time
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 OS 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.
Other Information:
After the snapshot has been copied to proxy and backed up, it is deleted from the primary storage
array where it was first taken.
Further enhancements are possible by providing multi-site disaster recovery by using low bandwidth
replication on HP D2D devices.
Using D2D in larger VMWare environments with HP Data Protector Zero Downtime Backup
with Instant Recovery (ZDB + IR)
Company requirements: Large VMWare environment, high throughput required to meet backup
window (Fibre Channel). High SLA s dictate an "Instant Recovery." High proportion of online backups
required.
Solution: HP D2D with VTL interface and separate VCB proxy server with Data Protector VCB ZDB IR.
Note that the VCB backup and the ZDB backup are completely independent of each other.
Caveats: Limited to arrays that support DP ZDB IR – XP, EVA and LHN (future).
