"Hello, is there a way to backup over an unstable WAN link (it is only short breaks so that the SSH tunnel is broken). I use rsync over SSH, unfortunately, fails the backup each time the line is broken.
Is there a way to restart the backup until it is finished? Now all backup stops and are discarded each time the ssh tunnel are broken and the backup will never be finished. Interrupted full runs should result in a 'partial' backup that is used by rsync to continue on the next attempt. However, because fulls do a read and checksum comparison on all data, continuing can still be a slow process even though it doesn't use the bandwidth to send matching data again. I don't think there is much you can do to improve that. Enabling compression on the ssh connection might help get more data across while the connection stays up. Turning on keep-alives in ssh might help if some equipment in the connection path is dropping the link due to idle time. You might use standard rsync to make a local snapshot copy of the target, restarting as needed, then let backuppc copy that to keep a history. " I thought of that myself earlier and it is worth trying. I will have to fix some script to establish the VPN tunnel but I guess I also can use it for other communications between my different places.
