VirtualFull backups be a partial solution to your problem. We have a laptop which we get very short backup time windows for -- never enough time to run a full backup. Instead, we run incrementals (takes about 20% of the time) and then run virtualfull backups to consolidate them. We never need to run real full backups. > If there would be something like a incremental forever feature in > bacula the problem could be solved.

I suggested a feature some time back which might help. I'm not sure if there's enough interest in it though. You can see this in the bacula projects file: http://bacula.git.sourceforge.net/git/gitweb.cgi?p=bacula/bacula;a=blob_plain;f=bacula/projects;hb=HEAD Item n: Implement a Migration job type that will create a reverse incremental (or decremental) backup from two existing full backups.
