It could one of several problems. What user did you specify to run the
scheduled backup? This user must have a password and sufficient rights to do
the backup. The backup will fail if the user doesn't have a password. The
next most common problem is with tapes. If the tape is different from what
the backup expects the backup will fail. To get around this problem you have
to run the backup from a script and schedule the script to run at the right
times. You either have to learn how the Removable Storage Manager works and
plan your scripts to use it or include the /um switch which will erase
whatever tape is in the drive. Here is a coupe of links to start you on the
way. It can be a long and winding road
