RAID5 only protects against hardware failure (and only some forms of hardware failure). There are still things like "rm -rf /" and other kinds of luser error to cope with. > I am wondering, have anybody had any experience with Bacula working on a > really large amounts of data? I'm backing up 30Tb here and we just bought up another 28Tb array which will fill up durig the next 6-8 months. The things to bear in mind are: 1: Do not try backing up all the filesets at once (I have 12 week cycle on full backups, with 2-3 full backups triggered each week instead of trying to backup 28 1TB sets in one go) 2: Keep fileset sizes sensible. We use a rule of thumb of 1Tb, which takes abour 20 hours on LTO2 (spooling plus tape run) and can run 2 of those simultaneously on each tape drive in the same time period (one spools, one despools, etc) ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
