I like how this backup has a really quick data retrieval method. When I lost my data a couple weeks ago on an app, I received it back within 5 minutes. Moreover the implementation of other Google products like Gmail makes it a lot easier to navigate and communicate data with my colleagues and send error and debug logs when necessary for recovery.
