## Restore
+Since RDS does **not** allow physical access to its managed instances, one **cannot** restore physical backups.
+It **does allow** restoring _logical_ backups, though.
+
+> [!warning]
+> RDS does **not** _restore_ data in the strictest sense of the word, e.g. by rolling it back or replacing it in the
+> same RDS DB instance.
+> Instead, the service forces users to create a **new** RDS DB instance from the desired backup point.
+
+Should one want to replace the data in an existing RDS DB instance, they **will** need to (either-or):
+
+- Restore a _logical_ backup via other means (e.g., `pg_restore`).
+- **Replace** the RDS DB instance with a new one from the desired backup.
+
+If an RDS DB instance **has automated backups enabled**, one can use it as source to create a **new** RDS DB instance
+that has the _same_ attributes and data up to a specific point in time.
+This does **not** modify the source DB instance.
+
+Refer [Restoring a DB instance to a specified time for Amazon RDS].
+
+One can restore to any point in time within the source RDS DB instance's automatic backup retention period.
+
+Restored DB instances are automatically associated with the **default** DB parameter and option groups, unless one
+specifies a custom parameter group and/or option group during the restore process.
+
+If the source DB instance has resource tags, RDS adds them by default to the restored DB instance.
+
DB instances **can** be restored from DB snapshots.
-Restoring instances from snapshots requires the new instances to have **equal or more** allocated storage than what the
-original instance had allocated at the time the snapshot was taken.
+This requires the new instances to have **equal or more** allocated storage than what the original instance had
