Is there any tool to backup/restore Google Datastore entities?

Question

I've playing around with Google App Engine and Google Datastore for a while now and I am facing the need to take regular backups of my stuff up on the cloud.

Is there any sort of general purpose tool that allows you to download all your data from a specific instance of google-datastore and restore it to another one?

If so, please enlighten me, if not - someone should do it!

You can use the BulkLoader that is described in the Google Appengine Docs

Answer 4

There is an opensource application available that I developed called "GAE datastore backup utility." It allows you to backup and restore your GAE entities through a GUI. It keeps track of your applications and your application's entities. It's currently only for Windows and Python based GAE apps but it sounds like something you are looking for. I see that you are looking for a solution for Java based apps. I will look into supporting this language in the next release.
