I think the workaround is to use rsync as transfer ;-) At least when you
added the "checksum-seed=" parameter to your config, it should
calculate the checksums on the client and compare with the servers
database and only transfer contents that differ.

Otherwise I would not manually fiddle with the dirs on the server, its
far less stress and risk for error if you just let backuppc do its
thing. Even if that means transfering the files again...

Have fun,
