Backup app kills the config.php file

[juliensl]

Hi everybody,

I am reporting an issue that can happen when backup app is uncorrectly used.

My problem appeared in 2022 April, but some people have it just few days ago, step to reproduce :

• Begin the backup
• Your disk become full because you do not have enough space
• The backup and server crash
• You delete the backup folder
• You cannot connect yourself again to your server because the config.php file has been cleaned

Exemple of a config.php file after :

$CONFIG = array (
  'instanceid' => 'oc8ig6j7n1sq',
);

Actually, thanks to @kyrofa, we succeed to re-create a new config.php file, so I do not need help anymore.
But the problem could happen for other people.

Maybe you should add a "space verificator" before to begin the backup, to not fullfill the disk.

To see all the sources, you can find my first post here :

And my comments here : nextcloud-snap/nextcloud-snap#2162

Just to know, I am using Nextcloud with snap on an Ubuntu server.

Thank you for your work !
