The fastest one I see is :
* mounting the backup on a server directory,
* export this directory from the server on NFS,
* mount this NFS share onto the client,
* client copy files from the mounted NFS share to the disk.

This way, the Id correspondance daemon will play its role and you
shouldn't have any discrepancy in (same) users numeric Ids.
