How do you back up multiple terabytes of data? [closed]

How do you back up multiple terabytes of data? [closed] While asking this question about a home NAS, Matt Rogish questioned my backup strategy for all this encoded video, and I had no answer. It seems that burning DVDs would be very time consuming. Also, do burned DVDs still suffer from degradation after n-years (where n is some number in the future)?

"There are some studies here that look into the long-term storage of information on DVDs. DVDs do end up suffering from degradation eventually - according some of these articles, you'd want to go gold-plated.

Personally, I would buy a few harddrives and use those for backup. You could even get a NAS that supports either RAID or JBOD (Just a bunch of disks) configurations and back up your data that way.

Edit: You might want to keep an eye on this question: What are my options for a multi-Terabyte home NAS?, as the devices they're discussing are what you could use."

"I bought three identical external disk drives, copied my data onto all 3, then plugged one into my HTPC, one into my home office PC, and one into the PC at work. I use Windows Live Mesh sync on each machine to keep them automatically in sync. The two computers at home sync over the LAN, and the office one gets updated eventually.

No reason this shouldn't work with one PC at home and one at work (or a friends), and you can always do it with more than one drive too."
