I've just started backing up my stuff with a method I think is pretty decent. I'll share it, since I'm kinda proud of it, haha.
I have two hard drives, a SSD as boot with all my programs, and a HDD with all my data.
I got a hard drive dock for my computer, so I can just plug in regular SATA drives into the front.
Bought a 500GB drive for 50 bucks and threw all the data I wanted backed up into a folder labelled with the date. Anyone know of a good rsync utility for windows?? I guess I could throw everything into the same folder and overwrite with the newer stuff. I'll figure that part out.
Second, I used clonezilla to clone my SSD as an image to the same hard drive. Now if something goes wrong with my os or programs, I can just restore the image and I'm back in business.
On my todo list for backup:
1) Figure out a good method for frequent data backups (ideally only transfering the modified information)
2) Get an off-site copy going (switch between two drives probably)
What do you use to back up all your precious stuff?
