Do you back up customer data?

A foundations question from almost every security questionnaire. Here is a model answer, the evidence a reviewer may ask for, and what to say if you don't do this yet.

A model answer

Yes. Customer data is backed up automatically [daily] and kept for [30 days], encrypted, in [a separate region or account]. Restores are tested [every quarter].

Replace the parts in square brackets with what's true for you, and only answer yes to what you do.

Evidence a reviewer may ask for

  • Your backup configuration in the database or cloud provider
  • The date and result of your last restore test

If you don't do this yet

Managed databases usually back up by default; say which service and its retention. If you have never tested a restore, don't claim you have. Test one and write down the result.

Answer it once, on your trust center, for every reviewer.
