Hi, I'm trying to configure a backuppc solution to transparently do a remote backup of laptops. The server is running ubuntu 8.04 with the packaged version of backuppc installed.
All the laptops are connected to the server's network using an openvpn tunnel (their upload bandwidth is supposed to be around 128kB/s), some of them are running windows (with rsyncd+cygwin) and others are linux machines (with rsync+ssh and keys). These laptops initially have a few GB of data to backup (not expected to change that often...) When I manually request a full backup of a linux laptop, the process starts and begin to fetch data from remote host. If I manually stop it for CGI interface, I get a clean partial backup. The problem is when a host disconnects from the network, backuppc doesn't seem to see that change and continues being in "backup running" state. After a long time (maybe around the 2-hours timeout or when the nightly wakeup occurs: both are possible in my test conditions!), the backup aborts and in the host summary I have a new full backup (not a partial one as I would have expected). As a consequence, even if the laptop reconnects, backuppc will not retry to get in sync. Does anyone know whether this behavior is normal? If I'm missing something, do you think backuppc could match my needs and what should I do to have the laptops being polled until I get one real full backup each day? I also have a remark about backuppc pooling feature: I think the server locally detects file duplicates by hashing them after download. As far as I know, rsync should also be able to send some kind of hash from remote host before download. Wouldn't it be possible to detect duplicates using this hash before the file is downloaded? This would for example save downloading files again when a user simply renames a directory...
