====== Android Backup ======

To backup your device, use this command. It will automatically insert the current date in the filename:

<code bash>
adb backup -apk -shared -all -f $(date '+%Y-%m-%d').db
</code>

If you are havong problems with the connection ("adb: unable to connect for backup"), check the listing of connected devices:

<code bash>
adb devices
</code>

Which may result in a listing like this:

<file>
List of devices attached 
????????????	no permissions
</file>

You can solve this by restarting the adb server:

<code bash>
sudo adb kill-server
sudo adb start-server
</code>
<file>
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
</file>

After this, the output of ''adb devices'' will look like this:

<file>
G65ABT632191	device
</file>

Now, try to start the backup again.
Good luck!
