Plan/B is a network aware file backup system specifically
designed to make the backup of files from multiple machines
to a variety of devices simple. The system includes
features such as comprehensive reporting, the ability to
use CDROM (and soon DVD) drives across the network and
centralised management. Plan/B can be deployed on Windows
and Linux systems.
The plan/b site has now been removed, primarily because it's no longer being maintained and also because of spam.
I'm happy to open source plan/b if I can find a maintainer for it. Keep in mind that it's a complex project, but hey - I'd be happy to make it available if people want. I've since moved onto Max OSX development and so have no intention of doing anything more on it.
