another solution... though not quite the best... create a pool and jobs specific to the PST file.. set the retention on the pool to be say 7 days.. That way you can backup/restore the pst file separately and not effect the backup of the rest of your system. Obviously you still have to send over

Sorry Bacula is not that clever..indeed it's just checking for files which changes.. It's not able to determine how the file changed, or just back up those bits which changed. ---Guy Sent from my iPad On 13 Jan 2011, at 20:44, Lawrence Strydom wrote: > Hi And thanks for all the replies so fa
