Hello, I am trying to backup a machine over a low bandwidth connection. Server is debian linux running BackupPC 3.1.0, client is Windows XP SP2 with rsync 3.0.4 (for more details see below). I am currently trying to run the initial full backup but it got interrupted twice already due to various reasons. When I retrigger the full backup, a lot of large files are retransmitted even though they have already been uploaded to the server and weren't even touched in the meantime.
In the log excerpt below you can see the processing of a file that definitely has been uploaded already. I am not sure if rsync transmits the file completely again or if the blocksize is so very small that the blockhashes are almost as much data as the original file. Whatever it is, resuming takes waaaay too long. Is it a problem to use rsyncd and pool compression in this scenario? Please help.
