Re: [Bacula-users] [Storage-Space usage] Prevent duplicate file-backups?

[John Drescher]

I have seen this discussed in this list before and I believe there are several problems on top of the small chance that a file will have the same size and same md5sum but different contents. One is do we only search (for dups) in the current backup job or volume or do we include other backups and other volumes.  If  we inclulde other  backups  how do we handle  the case where  a file from job X is on a volume from job Y because of a duplicate and now some user has purged that volume that contains job Y.
