Backups keep failing


Whenever I try and backup my site, I get an error.

I’m not sure what’s causing this. It was working fine before yesterday, when we moved to a new machine, which was fresh before we copied over the app.yml file to include our config.

Are you running discourse as root? What is the disk mapping (in the app.yml)?

Yes I am, and I’ll check the disk layout.

These are the disk mappings:

  - volume:
      host: /var/discourse/shared/standalone
      guest: /shared
  - volume:
      host: /var/discourse/shared/standalone/log/var-log
      guest: /var/log

Strange. I would enter the container and see what) whether that directory exists and if you can create a directory there.


Did you copy (parts of) the /var/discourse folder to the new server? That might have messed with the permissions/owner.


We ran the setup script, copied the app.yml, and restored from backup.

I will do that!
