Re: [Bacula-users] Avoid duplicate files
2011-09-15 12:56:39
Sorry, I really wasn't clear enough...
What I meant was that, in case of a Full Backup of a FileServer running Samba (which is my case), there are SEVERAL files on that server that are the same, they are just coped on several different folders (from different projects). I wanted to know if there was a way for Bacula automatically check for duplicated files before sending them to the Storage Daemon (maybe don't send the entire file, just a reference to the original identical file).
But your last comment answered my question, Bacula doesn't support it...
Thanks!

It's not clear what do you want in fact.
Incremental and differential backups are supposed to transfer only
modified files.
Then there are "base jobs" which can be used to define a minimal subset
of files which is supposed to be the same for several clients; this
also can be used to transfer only missing/changed files during backups.
If you're trying to formulate something like "FD-side deduplication", I
think it's not possible (and I doubt it'll ever be).
