+BREAKING CHANGE: DevX Backups can no longer be enabled via the `withBackup` prop, which has been removed.
+
+Users should now opt-in/out of DevX Backups at the construct level (i.e. when defining an RDS instance, cluster or
+DynamoDB table).
+
+We recommend using the `GuDatabaseInstance` or `GuDynamoTable` to help with this. If these constructs cannot be used,
+resources can also be tagged like this: `Tags.of(myDatabase).add("devx-backup-enabled", "true")`.
