is it compatible for Gingerbread Device? since i can't check on Play Store for while
well it would be great for cloud idea, but i do like if you add an option too to make a backup on /sdcard with .txt or something. since in my place, its not everyday you can get Wifi or using internet connection

Offline backup would be nice yes. I Should be able do reuse most code for offline and cloud backup.
