+### Backups
+
+Datastore backups are supported via AWS S3 and S3 compatible services like [minio](https://github.com/minio/minio).
+
+You may skip the `backup-auth` step if your dokku install is running within EC2 and has access to the bucket via an IAM profile. In that case, use the `--use-iam` option with the `backup` command.
+
+Backups can be performed using the backup commands:
+
+### set GPG Public Key encryption for all future backups of rethinkdb service
+
+```shell
+# usage
+dokku rethinkdb:backup-set-public-key-encryption <service> <public-key-id>
+```
+
+Set the `GPG` Public Key for encrypting backups:
+
+```shell
+dokku rethinkdb:backup-set-public-key-encryption lollipop
+```
+
+### unset GPG Public Key encryption for future backups of the rethinkdb service
+
+```shell
+# usage
+dokku rethinkdb:backup-unset-public-key-encryption <service>
+```
+
+Unset the `GPG` Public Key encryption for backups:
+
+```shell
+dokku rethinkdb:backup-unset-public-key-encryption lollipop
