I’ve always seen these self hosted S3 API compatible services as something a developer would use for testing.

Could maybe simplify the solution with https://syncthing.net/ or https://restic.net/ for self hosted backups.

For a couple reasons

1. Store and version configs in git. I realize unRAID provides flash drive backup (using git also), but this allows me to spin up my setup on another machine that may not be running unRAID. Helped recently when I switched away from Proxmox.

2. Allows me to group services with their dependencies. ( e.g. postgres, redis, etc ) Also can help isolate service groups from each other. Avoiding port conflicts on common db ports for example. Downside being may have more than one database, redis, etc.

Note, there is an unRAID docker compose plugin so you can still get easy access management buttons to start, stop, view logs, and edit services.

I have a very similar setup minus the iot and metric related services. I’m managing the services with Docker Compose on unRAID.
