In a proper disaster recovery plan, you have to be prepared for destruction of your infrastructure -- fire, flood, theft and so on. This means having offsite backup. I have much less data than you, under 80Gb. On my old server, I had a single drive set up with LVM. Then, I would snapshot the drive and sector copy (dd_rescue) the backuppc data to a removable usb drive for offsite storage. I recently set up a new server, and decided to store the backuppc data on a software raid1 mirrored pair, and then use LVM to snapshot it and copy to removable drive. Only problem so far is that I can't seem to snapshot the raid1 pair with evmsn. Since my server goes idle during the day, I simply stop backuppc, unmount the /backup partition, and sector copy. I don't think you will be able to get a removable drive in the size you would need, nor would you be able to get thing copied in a reasonable amount of time. You also have too much data for CD and DVD archive backups. You should probably be considering a fairly hefty tape drive. I can't advise you there, but I'm sure others can. If you have enough bandwidth, there are clustering systems out there that can work over a network cable, that I have seen, but not tried. http://www.it.uc3m.es/~ptb/nbd/ comes to mind.
