Re: [Bacula-users] deduplication within a volmue
For the bacula volumes it's not very high. It's in mostly in place to handle hundreds of thousands of wav files whose first 20-30% is the exact same content. To control the size of my bacula volumes I instead employee a very aggressive recycling policy on the pools. >From My Mobile On 5/31/13 2:22 Silver Salonen wrote: On Thursday 30 May 2013 21:36:52 melvin.r...@gmail.com wrote: > There is no dedup by default.

Re: [Bacula-users] deduplication within a volmue
There is no dedup by default. You have to either implement base jobs or do the dedup outside of Backus. I personally store my volumes on zfs and let it handle the de duplication.
