My complete backup solution is this:
I run "full" backups, five versions deep, to a NAS device. Incremental changes become the 2nd, 3rd, 4th or 5th revision. The 6th revision wipes out the 1st. Unchanged files do not get copied. I do this nightly. Would I grab the NAS device on the way out in a fire? Maybe, maybe not. But I would grab the two laptops if at all possible. This is with a 300Gb Maxtor One-Touch, in NAS mode, using the supplied Maxtor software. It also functions as a print server. For the truly curious it runs a stripped linux kernel + Samba off flash memory.
I also run a full backup to a USB drive which I keep in my office. Either I backup by bringing the laptop to work, or bringing the USB drive home.
Finally, once per year I archive everything onto DVD and keep them in my office as well.
As an operational step when dealing with photos, I don't format the camera SD chip until the backup has been completed.

The two times I've need personal backup restores, aside from user error (accidental deletion) have been for a mother board failure (my wife's laptop) and in that case I was able to put the drive in a USB enclosure so I truly didn't need the backup, and I had a hard drive failure in my laptop - manufacturing defect, when it was only 2 weeks old. With today's hardware and file systems, you are very unlikely to copy a corrupted file unnoticed. Still, server-class machines have ECC (error correcting) memory and RAID (redundant hardware drives) disks which further reduce the chance of hardware-induced data loss.
You could buy yourself $10M in life insurance, or a professional backup solution, but chances are neither one is cost-effective for the average reader of this post.
