Here is my current backup strategy (data only): Use Winrar to create a series of CD sized compressed archives. Burn each to CD.
Not fun. Ten CDs now, and growing. I can move up to DVD (and will soon).
I am concerned, though, about corruption. If one file goes corrupt, I understand I can bypass an individual file. I am also doing incremental backups quarterly (a single CD usually) with the full backup annually. I figure this way I have redundancy built in. CDs are stored in my safety deposit box.
My most valuable data is the pictures of my kids. I could never reproduce (obviously). I've even considered using GMail as a secondary backup source, but feel this is a bit unethical.
Anyone have any other advice to ensure that I keep my stuff safe? Any advice would be appreciated. Specifically, making sure I can get to the stuff on my CD-R's. But also, a fast, easy way to do incremental backups.
