- Amazon RDS for SQL Server now supports native backup/restore of TDE‑enabled databases on Multi‑AZ and same‑region read‑replica instances.
- Restores no longer require disabling TDE or moving to Single‑AZ; you back up the TDE certificate to S3 and restore with the TDE option enabled.
- Feature is available in all AWS regions that support RDS for SQL Server, simplifying HA deployments with encrypted‑at‑rest data.
