How do I make a temporary backup of the local datastore in the AppEngine SDK for MacOSX
And where are the files located?
Search for something called "local_db.bin" If you're using a plugin for Eclipse, you'll find this file in WEB-INF/appengine-generated
local_db.bin is the database file and it is located in your project directory, just make a copy of it.
