Your organization is subject to a regulation that requires all Google Workspace data for users in the European Union to be stored within the EU. You have already set up a data region policy for the EU. However, you discover that some user data is still stored in the United States. What is the most likely reason for this?
Data region policies in Google Workspace apply to data at rest for covered services, but they do not automatically migrate existing data. When you set a data region, only newly created data will be stored in the specified region. Existing data remains in its original location unless you request a migration. This is a common oversight when implementing data regions.
Why this answer
Data region policies in Google Workspace control where data at rest is stored for covered services. However, they do not automatically migrate existing data when enabled. Only new data generated after the policy takes effect is stored in the specified region.
To move existing data, you must initiate a data migration request through Google Support. Therefore, the presence of US-stored data is expected if the policy was recently applied.
Exam trap
The trap here is assuming that setting a data region policy will immediately relocate all existing user data, when in fact it only affects new data unless a migration is requested.
