What it is:

MongoDB Atlas now offers an additional, more secure option for exporting backup snapshots to Amazon S3 over AWS PrivateLink. While Atlas already supports backup exports to S3, this enhancement enables same-region exports to occur entirely over private endpoints, keeping all traffic on private IPs rather than public networks. Support for cross-region exports over AWS private endpoints will follow in a future release.

Who it's for:

This feature is designed for organizations that require private-only networking and strict data-movement controls, including those operating in regulated industries, financial services, healthcare, or environments where access to AWS services, such as customer-managed KMS keys, is restricted to PrivateLink.

Why it matters:

Exporting snapshots over PrivateLink strengthens your cloud security posture by ensuring that sensitive backup data never traverses public networks. Customers can maintain stricter network controls while continuing to benefit from seamless, automated backup exports to S3.
