That's true.

I triend once bacula for backups, but is too complicated for the simple setup 
I have. I just use KDE's "keep" (a rdiff-backup GUI). So easy, so reliable. I 
just have to make sure that the partition in my LVM that stores the backup is 
actually phisically located in a different HD to the source data. I had to 
setup two volumes to force that easily, but there are other ways acording to 
the LVM howto.

I have never tried LVM's snapshots... I wonder if they would be usable as a 
backup system.
