How Do You Backup 20TB of Data?
Sean0michael writes "Recently I had a friend lose their entire electronic collection of music and movies by erasing a RAID array on their home server. He had 20TB of data on his rack at home that had survived a dozen hard drive failures over the years. But he didn't have a good way to backup that much data, so he never took one. Now he wishes he had.
Asking around among our tech-savvy friends though, no one has a good answer to the question, 'how would you backup 20TB of data?'. It's not like you could just plug in an external drive, and using any cloud service would be terribly expensive. Blu-Ray discs can hold a lot of data, but that's a lot of time (and money) spent burning discs that you likely will never need. Tape drives are another possibility, but are they right for this kind of problem? I don' t know. There might be something else out there, but I still have no feasible solution.
So I ask fellow slashdotters: for a home user, how do you backup 20TB of Data?" Even Amazon Glacier is pretty pricey for that much data.

I would say use floppies, but I'm kind of old and out of touch now.
Figure out the theory of everything.
Then you can always recompute your data from scratch.
If Pandora's box is destined to be opened, *I* want to be the one to open it.
I do the exact same thing with high res pictures. I immediately will take the full resolution raw image and convert it down to a 320px gif. Or maybe a 10% quality jpeg. You get great economy that way too. Who wants to keep a 30+MB image around when you can have almost the same thing in 10kB instead!
Connect a raspberry pi and configure it as a backup server and let it copy all to /dev/null... ...
Then put aside the money you would have invested in a "better" solution, put it in a safe bank (under your mattress)
and wait until you need to restore something..
Most probably you'll enjoy the money more
