How about setting up rsync server on every box, acting as backup-point,
and then using BackupPC[1] (or any other rsync-based backup solution).
- From the point of view of security, you can only allow connections to
rsync servers only from backup machine. For Windows, there is an rsync
server port, named cwRsync[2] (based on cygwin).
