Is it safe to delete folders from the data/appdata_<instance_id>/<removed_app>/ folder for previously removed apps?
For example, I was using the backup app but I have just removed it from my instance. I would assume the respective folder within the appdata_<instance_id>/ folder would be automatically removed, but it was not. So now I have a huge folder with no use.
Would it be safe to just delete the folder? Or is it already automatically done via a cron job?
Here is my instance configuration:
Nextcloud version (eg, 20.0.5): 23.0.3
Operating system and version (eg, Ubuntu 20.04): Debian 11
Apache or nginx version (eg, Apache 2.4.25): 2.4.52
PHP version (eg, 7.4): 7.4.28
I have reinstalled and reactivated the backup app, then used the command occ app:remove backup to remove it. The behavior was the same as before, when I removed the app using the web interface, i.e. the app was removed, but the respective data/appdata_<instance_id>/backup/ folder was not deleted.
So how should I proceed?
Is it safe to manually delete that huge folder, i.e. rm -rf data/appdata_<instance_id>/backup/?
