backup app - creates no further restoring points

Nextcloud version: 23.0.3
Backup App version: 1.0.6
Operating system and version: Debian 4.19.235-1
nginx version: 1.21.6
PHP version: 8.0.17

After configuring the app and exporting configuration and key, I initiated the first backup by pressing the button Create full restoring point. After two days the backup had still the status “not packed yet”.

So I assumed a problem and removed the whole folder by:
rm -fR 20220218090002-full-27uyPwv6nMPWU8M
This was probably not good.

The Restoring point is still shown under “Restoring points history” as "processing" / "not packed yet"

occ backup:point:list shows

Now after pressing Create full restoring point again, it shows “The creation of a restoring point as been requested and will be initiated soon.” for a while. But after it is gone, no restoring point was created.

When I go to settings of the app, I get the message "Unable to fetch app data" for some seconds.

How can I analyse/repair the problem and start again with the backup app? The nextcloud.log shows no helpful information to me.

Thanks for your help

Start with the Backup app's restoring-point history and the occ backup:point:list output, then reproduce a new restoring-point request while monitoring nextcloud.log. Investigate why the existing point remains “not packed yet” and why the settings page reports “Unable to fetch app data”; done means the stuck state is explained and a new restoring point can be created successfully.
