Haha, if you read the error messages, you will see the problem: > (ssh-askpass:25663): Gtk-WARNING **: cannot open display: :0.0 > No protocol specified > > (ssh-askpass:25664): Gtk-WARNING **: cannot open display: :0.0 > No protocol specified > > (ssh-askpass:25665): Gtk-WARNING **: cannot open display: :0.0 > Tar exited with error 65280 () status > tarCreate: Unable to write to output file (Connection reset by peer) > restore failed: BackupPC_tarCreate failed Ask yourself, why is ssh-askpass running if you already have passwordless logins working? Answer... you don't have passwordless login working.

Sure, but if you are responsible for managing multiple linux machines, including the backup/restore of those machines, then you really should have some idea on what you are doing, and how to diagnose simple problems. Have you looked at the logs like /var/log/auth.info which probably has a record of the failed login? No conspiracy, just many people get tired or trying to help people that can't read the documentation. While many OSS has really poor/old or no documentation, BackupPC is very well documented. For all those watching on the side lines, test your backup *and* restore on a regular basis, and make sure you have documented your own environment. Get it working before you need it. When the crap hits the fan, there will be enough panic without also having to try and work out how your own backup system works. Sorry, my rant is over ... must be having a bad night...
