I meant MTF - Microsoft Tape Format.
The format that BackupExec uses to write data to the tape. AFAIK, all windows based backup systems will at least read MTF, and I beleive that they all use it to wite the data
What specific Event Log entries are you getting during the backups? Any alerts on the console? anything of note in the job logs?
As far as your selections. I's seriously look at why you are backing up individual mailboxes. They are totally useless for disaster recovery (but you are doing stores backups, so you are covered there), they are extremely slow compared to stores backups, when you go to restore them, you may have all kinds of problems (scan through the forums), and roperly managed, your Exchange system shouldn't require them. except for a few very high profile users perhaps.
It is a little dated by now, but take a look at http://mail.tekscan.com/nomailboxes.htm . It is a pretty good argument for NOT taking brick level backups
If you the backup window available, I'd stick with Fulls every night. Just be sure that the every second or third year you consider new hardware in your budget for the year. Remember that the new drive should be atleast read compatible with the old drive or your current tapes will be useless. (unless of course you keep the old drive on a shelf, waiting to be used :) )
