What do you use for backing up? Note: I have no confidental files. Music and Videos Either burn onto CD/DVD's, or upload them to MediaFire or something. Software Keys Google Docs. Also written down in a notebook. Documents Google Docs. Software Installers I burn them to CD/DVD's. Sometimes, if not available anymore, I upload (freeware) installers for friends on MediaFire. Pictures CD/DVD. Also ImageShack/Photobucket. Bookmarks Foxmarks. FireFox Addons I just write the names down and save them in Google Docs or something. Email I use Gmail, so don't need backup. Misc CD/DVD, or upload. Depending on what it is.
