The creation of the temporary backup file went smoothly. Its when the file is moved from /var/www/discourse/tmp/backups/default/ to /var/www/discourse/public/backups/default/ that issues surface. [2024-01-28 05:47:54] EXCEPTION: /var/www/discourse/lib/discourse.rb:137:in `exec': Failed to move database dump file. mv: cannot move '/var/www/discourse/tmp/backups/default/2024-01-28-054559/dump.sql.gz' to '/var/www/discourse/public/backups/default/hungry-onion-2024-01-28-054559-v20230728055813.sql.gz': Permission denied How do I address this issue? Separately, does this issue have anything to do with the fact that I previously created the /var/discourse/shared/standalone/backups/default/ folder (outside the container) myself when I used command line to restore a backup on a new instance? The permission right now is drwxrwxr-x 2 1000 www-data 4096 Jan 27 17:35 default

I am not really sure what happened. But yesterday night the system backed up successfully. Today I manually backed up also successfully. I made no change to the system between now and then. Oh well.

Those two locations are (normally) on the same disk, so it can’t be disk space trouble, so indeed I think it must be permission trouble. Of course backups will normally work - assuming you did a standard install - and so it seems likely that your manual creation of a directory has something to do with the trouble. But. I checked on my machine, and the ownership and protection is like this, inside the container: root@ubuntu-2gb-nbg1-1-app:/var/www/discourse# ls -ltrd /var/www/discourse/tmp/backups/default /var/www/discourse/public/backups/default drwxr-xr-x 2 discourse www-data 4096 Jan 24 03:36 /var/www/discourse/tmp/backups/default drwxr-xr-x 2 discourse www-data 4096 Jan 24 03:36 /var/www/discourse/public/backups/default root@ubuntu-2gb-nbg1-1-app:/var/www/discourse# ls -nltrd /var/www/discourse/tmp/backups/default /var/www/discourse/public/backups/default drwxr-xr-x 2 1000 33 4096 Jan 24 03:36 /var/www/discourse/tmp/backups/default drwxr-xr-x 2 1000 33 4096 Jan 24 03:36 /var/www/discourse/public/backups/default root@ubuntu-2gb-nbg1-1-app:/var/www/discourse# ls -nltrd /var/www/discourse/tmp/backups /var/www/discourse/public/backups lrwxrwxrwx 1 0 0 19 Jan 10 15:26 /var/www/discourse/tmp/backups -> /shared/tmp/backups lrwxrwxrwx 1 0 0 15 Jan 10 15:26 /var/www/discourse/public/backups -> /shared/backups root@ubuntu-2gb-nbg1-1-app:/var/www/discourse# ls -nltrd /var/www/discourse/tmp /var/www/discourse/public drwxr-xr-x 1 1000 1000 12288 Jan 10 15:31 /var/www/discourse/public drwxr-xr-x 1 1000 33 4096 Jan 10 15:36 /var/www/discourse/tmp root@ubuntu-2gb-nbg1-1-app:/var/www/discourse# ls -nltrd /var/www/discourse drwxr-xr-x 1 1000 1000 4096 Jan 10 15:26 /var/www/discourse root@ubuntu-2gb-nbg1-1-app:/var/www/discourse# ls -nltrd /shared/backups /shared/tmp/backups drwxr-xr-x 3 1000 33 4096 Aug 15 2019 /shared/backups drwxr-xr-x 3 1000 33 4096 Jan 10 15:36 /shared/tmp/backups root@ubuntu-2gb-nbg1-1-app:/var/www/discourse# ls -nltrd /shared /shared/tmp drwxr-xr-x 13 0 0 4096 Jan 27 2021 /shared drwxr-xr-x 4 1000 33 4096 Jan 10 15:35 /shared/tmp The 1000 user is “discourse” and the 33 group is “www-data” and all of this doesn’t give me a clue as to what your problem is. Sorry.

Can app inside docker see the system outside docker? I’m living in the believe it can’t be done that way.
