For backup and quick restore purposes, you could consider instead (or
additionally) doing a "hot backup". Your backup is then a complete
repository which you can use immediately without having to load it
anywhere. You're back to work as quickly as your OS / hardware can
copy the backup onto the primary disk(s), or quicker if you keep a
copy of the backup on the same disk(s) as your main repository.
