Chiron FS lets you set up RAID-1 over the network

Posted by: hickinbottoms on June 11, 2008 12:41 PM
Don't forget Box Backup (http://www.boxbackup.org) if your goal is an off-site automatically synchronised backup.

It has the same basic requirement (a low performance computer as the server), but has some nice advantages such as encrypted backups (so you don't have to trust the internet or the site hosting your backup), diff-based backups so bandwidth usage is minimised, and keeping as many old and deleted versions of the file as the space on the server will allow. It also doesn't rely on the network connection being always-on, and a single server can support many clients whilst maintaining the privacy of each client's backup.

As normal filesystem reads/writes are never over the network local disk performance doesn't suffer.

All-in-all a very good solution in my experience.
