You're right. I just have to find a way to implement it in the backuppc
backups. It would be awefull if the 'restore' function from backuppc
would still work for Data.fs directly, but that's only possible if the
backupped Data.fs from repozo.py is stored as instance/<name>/var/Data.fs
in backuppc. I doubt that this is possible in an easy way.

I'll see. But for sure something has to be changed ;-)
