> [backup on harddisk]
CDs won't really cut it for me either. CDs have very limited capacity. Same story with DVD or even tape backup, unless I am prepared to spend mucho pesetas. (IBM has a pretty cool looking 100 GByte tape drive. The tapes alone go for a couple hundred US bucks.)
I recently added a Promise RAID SATA controller and two SATA disks (160 GByte each) to my system. The Promise does hardware RAID 0 and 1 (I don't remember whether it also does 0+1). I'm using mirroring.
All the important data is now on that "one mirrored disk". If one of the physical disks fails, I can simply install in place of the failed disk a new disk of equal or greater capacity to restore the mirror.
The Promise has four SATA ports, enough for two disk pairs, and I'm thinking of adding the second pair, as I need additional "mirrored" capacity for an upcoming project.

I have a startup drive with applications, etc which gets backed up/duplicated to one hard drive nightly.
Then I have a striped RAID setup for scratch and large file work.
Then one disk with photos/scans.
Then one backup disk which gets powered up and the photo/scan disk gets duplicated.
After that the disk gets powered down and exchanged for the other backup drive which gets stored off-site and that is the next one that gets the backup. This way the most recent backup is always off-site, and the backup drives get very little run time, and will therefore last a lot longer and be a lot more reliable.
I had done something like this before, but perfected this setup on the advice of someone who now is one of the technical directors of Google. It might be overkill, but I know now that my images are probably as safe or safer than my film negs.
