(AFAIK, bacula compresses each file seperatly, so having 20 copies of the same file takes 20 times as much space as having one copy of the file, with or without compression.)
I never checked, how does bacula report the size of sparse files in the backed-up data? Maybe he has a couple of really large sparse files. ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
