A multiplatform GUI application I coded that uses ADB Backup to make full backups of your phone/tablet.
Unfortunately, ADB Backup itself is rather buggy so it will often fail on many devices, and may not work at all on some (the HTC One series and Sony phones from 2011 are most often reported to not work). All of the things the Ultimate Backup Tool has trouble with also affect this application. Sorry, that's just how it works. Do report devices that don't work though, just so everyone knows about it.
One of the best uses of ADB Backup is backing up Nexus devices before unlocking the bootloader, which wipes the device. You can then simply restore the backup to have your device in (mostly) the same state as before.
Tested by myself on Windows 7 and Linux Mint 14. As I've only tested it on my own phone, I'm treating this as an open beta.
Download
http://www.mediafire.com/?t489d99hthqx4xv - Contains source and executables for both platforms.
Usage
On Windows, simply run SAB_Windows.exe.
On Linux, run SAB_Linux as superuser (easiest way is just 'sudo ./SAB_Linux').
You can also run it from source on either platform, run main.py on Windows and main_linux.py on Linux. The only dependency is Python 2.7 and PyQt.
Source
https://github.com/omegavesko/SimpleADBBackup - It's rather messy, I'm not too good at keeping git repos tidy. Should still work, though.
Changelog
v1.0 - Initial release.
