Bacula to my knowledge does not have this capability. I got around it myself by using an appliance like from DataDomain that does the deduplication and compression itself, which works and gets a better compression ratio than any software I know of out there besides EMC's Avamar but I won't go into details about that low level non working piece of software that doesn't work with any existing backup software.. ;) -Drew ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
