Reclaim Deduplicated Space on a Server 2012 Server
Posted on 2014-10-03
Hello. I have a server 2012 veeam backup server that has been storing our Veeam Backups for the past 9 months. That backup archive volume is 26TB which now only has 3 TB available. We were able to achieve a 73% deduplication rate.
Our weekly full backups are 4 TB so we are now out of space. I have gone through and deleted 4 months of backups but since they are deduplicated I don't get the space savings back that I thought I was going to get.
I have stopped the current running deduplication job until I can fix this issue. I have ran the full and basic garbage collection job but have been unable to reclaim enough space to store new backups. It only freed up about 2 TB or so.
Start-DedupJob -Type GarbageCollection -full -Memory 85 -Priority High -Volume A:
Does anyone know how I can reclaim space on a deduplicated volume?
