OK, here's my truly OCD plan that I've been using a while now:

It look smore complicated than it is. basically, every day, I pull a disk out of my backpack, put it into a drawer at work, and put the disk that was was in the drawer in the backpack.

When I get home, I pull out the disk in my backpack, hook it to my laptop, start a full backup, and when that starts, I take the disk on the desk in put that into my backpack.

This is just for incremental, day to day stuff. There's also a Deep-storage server which is a Snap server for now, but will soon be a NAS. I don't trust optical storage after my 2003 photos on CD developed oxidation. The magnetic media still read fine. Currently, I deep-store to a combination of flash drives and magnetic media, and about every 18 months, I push files onto newer hardware. I know it's obsessive, but it's simply the care level needed for data like family photos and videos, which as irreplaceable and too important for me to push into some online service that might vanish one day.
