I would suggest adding some protection into the script.  Before
relabeling the volume, you might consider making the volume read-only
first.  If those succeed, it can't be used by a backup.  If it's being
used by a backup, I suspect the read-only will fail.

At that point, you can relabel and the read-only designation will
disappear.
