I seem to recall a surge of reviews on workgroup oriented pre-built servers (with backup tape included) based on Linux - but now I can't find too many options.

A small client of mine needs more disk space so I wanna suppliment their existing NT server with a Linux box for file sharing. I know buying backup software to handle their existing NT server PLUS the supplimental server would be expensive (gawd) so I'm looking for a machine with it's own backups.

Recommendations welcomed.... Machine and/or multi-server backup software.
