In online backup for me the google drive is the best for that. It tracks your changes too, so if you make an edit to the document and hit save, you can still look back at all your revisions from the past 30 days. Of course it relies heavily on Google search, with image recognition for browsing your photos and some OCR capabilities for sniffing out text in pictures. You’ll be able to open things you saved in Google Drive using other service; it can handle more than 30 different types of files, including Adobe Illustrator and Photoshop and HD video, and you don’t even have to have those programs installed on your computer. So for example, if you squirreled away a music file, you could listen to it later on whatever player you please. Drive also pretty much does away with email attachments, which makes sharing a lot easier. If you wanted to show a friend a video of your vacation, you could just pass them a link to that file, rather than adding it to a clunky message. Essentially, it’s a beefed-up version of Google Docs. You can store your documents, photos, music, videos, etc. all in one place. It syncs with your mobile devices and your computer, so if you make a change from one gadget, it will automatically show up if you were to access it elsewhere.
