Raw services or in containers?

Thank you, that’s what I thought. However, I’ve been wondering what would be a reliable way to backup my services (for example, if i need to replace/format my OS without losing service states).

Also, sometimes my dietpi freezes and I lose access to all my services which is terrible. For example, right now, I’m out of my hometown and I lose access to plex and my services because some point of failure which I’m yet to discover what is causing it — opened a thread regarding this here
