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!
