Is this dump/restore the extent of what Google will provide? Two limitations offhand are: 1. If your application has multiple entity kinds, then you need to download all of them individually. If you have a complex app with lots of entity types, you have to customize the script. 2. If something goes wrong with your data, and you try to return to your restore point you still need to clear out any entities that were added after your restore point.
Understood - we can "roll-our-own" solutions to these and all other issues associated with reliable backup and restore. But robust backup/ restore really needs to be implemented as a foundational element of Appengine.
