Why not have a script that runs a backup followed by an archive. Check
the error code of the backup, if is not 0 then don't run the archive. If
it is 0 then run the archive which will automatically delete the files
when it completes successfully. It will not delete antything if it fails
even with a 1.

Regards,

Patrick Whelan

The problem with that is two-fold:

1. We backup multiple copies of the data, therefore, the archive option
will not work. 2. What if a tape has an I/O error half way through the
archive process? Yikes.
