Hello there,
when deploying BE 2010 R3 for use with AVVI and deduplication, as per your experience does it make sense to create an initial "gold" full backup to a dedupe folder that will not expire/be overwritten then perform deduped full backups forever ?
Can anyone please share som field experience ?
Thanks and Regards,
Massimiliano

It doesn't matter. BE will retain the blocks of data it needs, regardless of the append/overwrite periods. So you do not have to pre-stage anything and keep it "indefinitely."
You also if capable (vSphere 4+ and HW level 7 VM's) would want to implement Full/Incr or Full/Diff AVVI backups and not just fulls everyday from a capacity standpoint. This would would ensure that the index database doesn't grow too large, as well as not grow the dedupe folder larger/faster than anticipated.

Hi Teiva-boy,
From what you are saying then, the key thing disadvantage to doing continual fulls is the indexes will grow to quickly and be more of a hassel to manage. I have wondered in the past why people wouldn't do full backups forever.

The dedupe process works like this (mind you this is very high level):
So here is where things get interesting from what I just wrote...
While you could do fulls all the time, it's not recommended, and you should just continue to do backups as you did in the past with a traditional full/incr or full/diff methodology.
