I've been wanting tape backup for home use for a couple of years now but haven't been able to afford any yet. I recently bought a new battery and some new casette tapes for my old digital camcorder. Just now I came to think, perhaps I can put backups on these tapes? I did an internet search and found this. I have not yet had a chance to test the tools mentioned in this article since my current desktop computer is lacking any firewire ports.
It is not advisible to have this as the primary method of backup but I found it interesting still and will personally be doing this in the future just for the fun of it.
