Longtime ago, I did the some on a ZIP drive.
I used "automountd" I think, I'm sure about "auto" not about the remainder
The ZIP drive was unmounted when unused for more than 5min.
And remounted when trying to access is mounting point.

I googled a little but did not find anything.

Otherwhise you can suppose your employee will change the tape at
a know time and add a script in the cron to dismount 1H before.

Also you con dismount the drive using "plink" utility from window's
putty package,
from your windows server, when your backup is done!
