So I can expect that whatever is under the hood for Bacula to get me some compression (I agree with the 1:1.5) for the tape drive. I'm trying to see how much space I need to back up three macbooks and three debian servers. Using my own macbook as the worse case situation I have 20GB in $HOME, 21GB in /opt, and 66GB used in total. Sorting out junk and stuff that I can reinstall via ports, I have 40-50GB of usable space that I'll eventually need to keep backed up. As a guess I assumed 1.5 to 2.0 times more space in a backup of said computer. So this means I should have ~80GB for one macbook. Something like that. Those calculations? ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
