Backup exec fails: puts back-up on hold?

[LastWords]

I run a daily backup that is supposed to overwrite media (level NONE). However when I run the backup it gets nearly to the end (5-10% till completion) then it puts it on hold (failed). How can get I get backup exec to finish with a 100% backed up?
Any suggestions welcome.

Check the error log. Your job is likely holding on a network attach or log in to a program (Exchange or SQL). In addition, your jobs can fail in verification if you have one or 2 corrupt e-mails. Yes a few corrupt files can cause the entire backup to say it failed.
