Then I heard about Dropbox from some other authors. This is a free program if you don't use up too much bandwidth, and I just save text files. Not only will it let you back up files (in one of those cloud locations or whatever you would call it if you were tech-savvy), it does it automatically when you save. And you can keep your files synced between computers. If I save it on my laptop Dropbox folder, it’s saved on our desktop computer's Dropbox folder. And vice versa. I can also share files with others. And if I had an IPhone I could sync my files there. It even works with PCs and Macs.
