This script will backup filesystems by taking the mirror offline and
dumping it.
Redundancy will be lost for the duration of the backup and regained
when the mirror resynchs - after the backup.
note the size of /dev/md/dsk filesystems, you may require more than one
tape.
Filesystems will be dumped in this order:
