BTW, what is the possibility of having backuppc request the first 100k or whatever of a file is needed to calculate the pool checksum, then see if the file exists in the pool, and then we wouldn't need to re-download (for example) the 30M linux kernel package, or the 300M windows sp3 file, etc... This would also solve the issue of renaming files/folders... Can the rsync protocol handle sending just the first portion of a file? Of course the full file checksum would need to match as well :) probably if we find a match in the pool. then re-start the transfer with this target file, so that we will run the checksum over the entire file...
