AFAIK UUIDs are unique to the device and to the partition. You can't
back them up or restore them to any device. If I'm wrong on this please
say so, I'm willing to be wrong.
Also, it seems to me that a backup solution for encrypted data should
backup and compress the unencrypted data and then reencrypt it. Your free
to do the backup of the whole encrypted partition though.
