Here is a script file I have in the /root directory.
It is named flexbackup-restore
I chmod it with a +x to allow execution.
cd /home/e-smith/files/ibays/restore/files
/bin/mt -f /dev/nst0 rewind
/bin/mt -f /dev/nst0 fsf 1
/usr/bin/flexbackup -restore
/bin/mt -f /dev/nst0 rewind
This will allow you to easily test the backup by restoring one or more files, if you're worried about it, or if you want to restore files for a user.
FYI - the ibay I use in the example above is named "restore".
Any file you add to the restore will end up under the restore ibay.
