How about the old method of backup tape? Using LTO2 tape, you can backup enough today (based on your estimation of ~120GB per backup), adn in the future. It's not cheap, but it does the work.

Folks -

We are looking for some backup solutions for a Linux based file server. Up until now we have been burning DVD's, but as the volume of files grows that is becoming a less manageable solution. In general we are talking about amounts of up to 20Gb per backed up volume with about half a dozen volumes.

Ideally we should be able to backup multiple full copies (over time) of a volume (Weekly backup for example), coupled with incremental backups of the volume (Daily backup for example).

One option that comes to mind is a dedicated file server, but that means that the backups are not physically removed. On the other hand using removable disks (USB2.0/Firewire) means that we dedicate a significant storage capacity (And cost) to each backup.

Ideas anyone?

   Thanks in advance
