Issue on Chunk when packing backup

[Tomptez]

Hello, I was able to create a backup point (first pass) but was unable to pack it.

sudo -u www-data php /var/www/html/nextcloud/occ backup:point:list

returns:

- retreiving data from local
 > found RestoringPoint 20220112111713-full-lQoHZL8oq5FL82h
- retreiving data from external:7

Any idea on what's the underlying issue or how I could get more information on it?

you can try running the packing job in verbose mode:

sudo -u www-data php /var/www/html/nextcloud/occ backup:point:pack -v 20220112111713-full-lQoHZL8oq5FL82h
