SBS 2003 Backup Issues
I run a backup every night on my SBS2003 server. Instead of tape, (which I consider to be slow, clunky and overpriced compared to modern-day alternatives - But that's a matter of personal opinion!) - We use 5 external hard-drives, rotating daily - Which are taken off-site for safety.
The backups have been going fine, but now the drives contain a fair few backups, they are beginning to fill up. Last night, the backup failed for the first time.
Here's a copy of the backup log:
I have researched this, and there is only *Just* enough free space on the drive to complete the backup. This happens on any hard-drive I try out of the 5 I have.
If I delete all but the most recent bkf file from the hard-drive and run the backup again, it's fine! It's almost as if ntbackup isn't correctly calculating free space and over-writing the last backup.
Thoughts please!

Any idea how I can pre-launch a .bat when the backup starts?
I'm not using a batch file to initiate the backup, I've done it through the wizard.
The scheduled task has the following shortcut path:
"C:\Program Files\Microsoft Windows Small Business Server\Backup\bkprunner.ex e"
I'm unsure as to the syntax for the batch script also. The freecom external drives I'm hot-swapping have 149GB of usable space, and the backups reach 33.4 GB (35,960,156,160 bytes) per day.

Infact to be honest, I think this setup could be simplified by having differential or daily backups instead of a full backup every day - That would more than likely solve the problem, as they only keep a weeks worth so the drives would never become close to full before being overwritten! This is a much simpler solution :-)
Thanks for your help everyone!
