How to backup and delete plugins?

[pHneutre]

I saw on previous posts that I simply need to delete the plugin folder in /app/code/plugins.

1. Could this be added to the docs please?
2. I would like to backup the plugins directory before proceeding. For this I'm trying to mv plugins plugins.backup but even with gosu cloudron:cloudron before, it fails as parent folder is read-only.
   What is the standard way to proceed?
3. Cloudron is not a Discourse-supported way of self-hosting so docs is scarce. Is there an app.yml somewhere (couldn't find one with find) that lists the plugins or has this been removed?

(I'm on Discourse 2.8.14 if that matters)

I'd just do a full Cloudron back-up of the Discourse app before deleting that folder. Give it a suitable label, and make it as one not to delete. See https://docs.cloudron.io/backups#backup-labels
