Re: [BackupPC-users] Howto backup a laptop (with a dynamic IP behind a firewall) via SSH-tunnel?
2008-04-29 23:52:35
You could install cygwin/rsync on the windows machine and build a script to ssh to the backuppc server and make an alternate-port like 45000 rsyncd tunnel. set the client config to backup localhost:45000 and have the remote client's rsyncd set to port 45000. disable automatic backups in backuppc and set the windows scheduler to run the script. You could also use putty but would still have to install an rsyncd server such as cygwin or deltacopy.
you would either need to use the Backuppc_dump so the tunnel stays connected or you would need to also run a `while [ps -ef|grep -e Backuppc_serverMsg -e $yourclientname]; then sleep 5; else exit; done` after the backup command so that the tunnel stays open until that backup is finnished or killed. that would be a fairly elegant system except that the putty windows for the tunnel would be blank, unless you added some sort of message or add a `Backuppc_serverMsg status jobs`. additionally, you could use puttyfile(putty that uses config files instead of the registry) to make a deployable package with NSIS installer.
only problem is that all Backuppc_* commands need to be run as user backuppc so you would need to adjust your sudo settings to all ONLY these programs to be run with sudo without a password.

Hamachi is proprietary stuff. I wouldn't like being dependent on their
central servers, proprietary client etc.
Better use OpenVPN and get that one OpenVPN port through the firewall.
