+### Minio S3
+
+[Minio](https://minio.io/) is a distributed object storage server, providing the same API as Amazon S3.
+Since Cloudron supports S3, any API compatible solution should be supported as well, if this is not the case, let us know.
+
+Minio can be setup, by following the [installation instructions](https://docs.minio.io/) on any server, which is reachable by the Cloudron.
+Do not setup Minio on the same server as the Cloudron, this will inevitably result in data loss, if backups are stored on the same instance.
+
+Once setup, minio will print the necessary information, like login credentials, region and endpoints in its logs.
+
+```
+$ ./minio server ./storage
+
+Endpoint:  http://192.168.10.113:9000  http://127.0.0.1:9000
+AccessKey: GFAWYNJEY7PUSLTHYHT6
+SecretKey: /fEWk66E7GsPnzE1gohqKDovaytLcxhr0tNWnv3U
+Region:    us-east-1
+```
+
+First create a new bucket for the backups, using the minio commandline tools or the webinterface. The bucket has to have **read and write** permissions.
+
+The information to be copied to the Cloudron's backup settings form may look similar to:
