Sorry, I was being "cute" - which is really dumb. The swapped-out disks (in this case, in ViPower swap trays) are physically removed from the system and placed in a locking fire resistant file cabinet. There is no electrical connection, hence an "air gap" between the backup server and the rotated drives. Offsite, under lock and key, would be even safer, but much less convenient. Without an "air gap", the drives are potentially vulnerable. I rotate 3 backup drives, 500GB Seagates, in a random schedule. The drives are labelled "P500, Q500, and R500", and will probably hold about a year of backups among the three, if they don't fail. I have had some backup drive failures ( mostly Maxtors ), but beyond that I have daily backups going back to ( A200, B200, C200 ) in 2003 . These drives are all bootable (there is a 4GB bootable partition and a swap on each one) so I can boot from them and copy images onto a replacement client drive (which I have done 4 or 5 times now, sometimes just for practice). The "copy machine" is isolated from the net, and I can perform the restores using a live CD if I am really paranoid.
