One the filenames: As they don't matter it might be nice to give them there original name and directory structure for transparency outside backuppc. Not sure if hashing the entire file is a good idea, at least not by default. Unless you make sure that the hash is only computed occasionally this will really hurt performance. It's why --checksum isn't the default with rsync. >I'm not going to discuss this proposal any further.

They stop otherwise healthy discussions. That said, you may be right here. If only because implementing your proposal may imply changing a lot of the core structure of backuppc and a fresh start, stealing some pieces from backuppc, might be a better approach. BTW, I barely understand how backuppc is working. It's workings are surely not ingrained in my mind. On the contrary I am still struggling to understand why distinguishing full and incremental backups is necessary if one uses rsync. To me it this seems like a relict from tape archives. Same for doing full based on the last full, not the last filled-in incremental. ...
