Kind of off-topic for this list unless you are just using subversion for
backups, but backuppc (http://backuppc.sourceforge.net/)is a good
solution if you can put it on a central Linux server (with
linux/windows/mac targets). It uses pooling and compression to keep
more history than you'd expect on line and available through a web
interface.
