Sudo mkdir -p /volume1/docker/minio/config Just ssh into your Synology NAS with your administrator username/password: ssh directories for the data and configuration (these live outside the Docker container): sudo mkdir -p /volume1/docker/minio/data We weren’t able to successfully create and run a Docker container through the Package Center UI, but it was easy via the command line. Click on minio/minio in the search results and click Download.

In the Docker window, click on Registry.

Click Install next to Docker in the search results.

Check Synology’s web site to make sure our model is compatible with the Docker package: Synology Docker package page.

Here are the steps we took to get Minio installed on our Synology DS218+:

If you install Minio on your NAS (Synology supports Minio via Docker on many of its NAS devices), Arq can back up to your NAS using Minio and get benefits over SFTP like atomic writes of files (faster and less error checking required by Arq), checksums of uploaded data (so Arq can verify the NAS received the correct data), and much faster validation of data (comparing checksums instead of downloading data to compare). Minio is an open-source S3-compatible storage server. Arq can back up to any folder you want, so you could configure it to back up to a folder that lives on your NAS, but there’s a better way: use Minio!
