How to backup the application's database to the Google servers

I'm developing an application which will do the backup of Application's database to the Google servers and restores the data after reinstalling the application.

I didn't find any ref开发者_JAVA技巧erence to do this task. and one more thing, i tried the application given in the Android SDK, which is working only with the Shell commands but not by running the application.

Could any body is having an idea how to do the backup and restoring of the Application's database data?

I believe this feature was added in Android 2.2
