Flashbackup and Deduplication

Created: 17 Oct 2013 • Updated: 18 Oct 2013 | 4 comments
This issue has been solved. See solution.

I've been bouncing around the documentation but haven't got this question answered yet.  I know Flashbackup grabs the entire disk and then you can do flash incramentals.  What I was wondering is if a flashbackup can be placedon a deduplication pool/disk and be shrunk that way?

Moved to NetBackup forum since question is not directly related to NBU Appliances.

Well I think you can put flashbackup policy on a disk pool. So why don't you just try it. I think you should gain some space for instance from empty blocks backed up - which should greatly 'dedupe' and compress.

Mostly I'm looking to see if. 

  1. Anyone had done this.
  2. How well did it work for them?
  3. Any gotchas that exist.

 

Thanks,

Hey Sully,

 

I am doing this right now

It works well for us

No gotchas!

We backup to a farm of  ExaGrid deduplication appliances which have CIFS OST shares presented to the netbackup server. I backup 2 seperate VM environments to them, and I get 8 to 1 compression on one environment and 10 to 1 in the other.

 

With this appliance and in our configuration it seems to work great, its easy to present new shares and the compression we get is great. We are able to keep 3 months of backups on disk this way, which makes most restores easy to do, without going to a tape.

If I was helpful in solving your issue please mark my post with a thumbs up or a solution!  Have a great day :)
