We've mentioned the S4BB data backup solution here on the blogs before. Of course, this was way back when it was intially released. Now, S4BB has put in a lot of bug fixes and updated the application to have more features. Essentially if you are in need of a data backup solution and don't mind being a beta tester, this is something you may want to look into signing up for.
Rather then making use of cloud storage, DataBackup stores al your information directly to your already in place SDCard or internal device memory. Cloud storage is always a good option but personally, I like to keep my backups in more then one place. Running this app and a cloud based solution helps keep a back up always available should the need ever arise.
