Here is feedback from the customer.

Following the guide [1], undercloud restoration was not succeeded.

Swift objects could haven't been downloaded after restoration even
though they followed all procedures during backing up / restoring
their system described in [1].

Since that, I'm not 100% sure if `tar -czf` is good enough to take a
backup of the system or not.

It would be great help to do dry-run against backed up data so that we
can make sure that backed up data is completely fine.
