+`minio-backup-s3` is a service giving you ability to mirror entities from `SOURCE OBJECT STORAGE` to `DESTINATION OBJECT STORAGE`.
+
+## Docker
+
+```sh
+$ docker run -e MC_HOST_SOURCE=https://<Access Key>:<Secret Key>@<YOUR-S3-ENDPOINT> -e MC_HOST_DESTINATION=https://<Access Key>:<Secret Key>@<YOUR-S3-ENDPOINT> fandoghpaas/minio-backup-s3:<IMAGE_VERSION>
+```
+
+
+## [Fandogh PaaS](https://docs.fandogh.cloud) Manifest
+Copy below manifest in a YAML file and enter `fandogh service apply -f <FILE_NAME>.yml`
+```
+kind: InternalService
+name: minio-backup
+spec:
+  image: _/fandoghpaas/minio-backup-s3:1.0.0
+  image_pull_policy: Always
+  env:
+  - name: MC_HOST_SOURCE
+    value: http://<Access Key>:<Secret Key>@<source-minio-service-name>
+  - name: MC_HOST_DESTINATION
+    value: http://<Access Key>:<Secret Key>@<destination-minio-service-name>
+```
+
+## Variable Table
+
+>  **Before deployment** value of `variables` mentioned in this table should be overwritten with values of your choice.
+
+|Variable | Description |
+|--- |--- |
+|**MC_HOST_SOURCE** | Choose source MinIO endpoint url
+|**MC_HOST_DESTINATION** | Choose destination MinIO endpoint url
+|**SCHEDULE** | backup schedule time for cronjob, see explanations below
+
+
+## SCHEDULE
+You can set the `SCHEDULE` environment variable like `-e SCHEDULE="@daily"` or `-e SCHEDULE="0 0 */4 * * *"` to run the backup automatically.
+
+> If you don't enter SCHEDULE env, container will perform its actions only one time and terminate!
+
+More information about the scheduling can be found [here](http://godoc.org/github.com/robfig/cron#hdr-Predefined_schedules).
