Re: [Veritas-bu] VM File Level Backups and not Full VMDK withfilelevel r

Mikhail,

I'm not following what you're saying. NBU can restore granular files from a CBT enabled backup. How does Avamar differ from that?

Hello Bahadir,

I have mentioned that NBU does support for CBT during backup. Unfortunately it does not support it for restores, because you still have to recover full VMDK image and apply CBT incrementals. Other solutions (Avamar, for example) don't use the full VMDK for recovery if they need to recover just a few blocks.

WBR, Mikhail

Mikhail,

NetBackup does support CBT in VMware backups.
Even, you can restore a single file from CBT enabled backups.

Depending on the NBU version, you need to modify the FlashBackup-Windows policy appropriately.

Bahadir.

Additionally to CBT backups, Avamar can also leverage CBT during restores. This feature could be useful if you need to restore a VM of several hundreds of GBs: it will only recall bytes that have been modified since last backup from backup. Looking forward to see similar feature in NBU.

What do you mean "File level backups?"

There is either image level (entire VMDK) or guest level (agent within guest) Which NBU can do both, among many other backup vendors.

VCB is so last year. the new vStorage API's can use Change Block tracking (CBT) so you dont have to send the entire VMDK each time. This was a VCB limitation.

I know Avamar is one great solution that takes CBT even further by deduping even the CBT blocks.
