How do I recover production data in App Engine that I accidentally deleted?

Question

I deleted some data from my production App Engine app. Unfortunately I had the wrong table name in mind when I did so because I have two tables that have very similar names. I know the deployed code is versioned so you can roll back to a previous version of your code. What about for your data? And, going forward, what's the best data backup strategy to use for production data?

Answer 1

Sorry Keith your data is lost. Backups are the responsibility of the user.

There is a feature request Datastore archive which you should star if you think something like this should be part of the service and an improved Import/Export is on the roadmap.

For now your best options are:

• Use the Bulkloader to fetch all your entities
• Write a custom offsite backup script that fetches important parts of your data via remote_api
• Periodically copy all your entities into a different namespace in the datastore (this can be trickier that it sounds)
