A friend of mine recently lost her computer to a hard drive crash. She lamented the lack of recent backup. On another writer's loop they discussed on-line back up storage. Some pay for it. Some are free if you don't have much to store. I back up my work on flash drives these days. My son asked me the other day if I still had copies of all the books I've written. I do... some hard copies, some still on those small A drive discs... LOL.
One friend said she had more than 2G she needed to store and paid for unlimited on-line back up. Another friend swore she was getting an external hard drive.
I scratch my head... what do you back up? I back up my stories. (Even with all my work I don't have more than 2G) Otherwise I have hard copies of query letters- and hard copies of charts of who and what went where. I suppose you could back up photos...I did store those online until they started charging for the pleasure...
Let me know what you back up and where- I'm curious... :)
