I try to schedule the backups so that they start after everyone leaves,
but sometimes people are working on their Access Databases when the
backup kicks off.

We have OFA, but almost every night lately, it complains that "some" (it
varies) .MDB is "corrupt on media", which results in an error, and then
of course, the duplicate to tape job won't run.

I can assure you that the MDB file is NOT corrupt.

Any ideas?
