From the screenshot this looks like a configuration error. Backup app is working for me on NC25.

Nextcloud: 25.0.2 (via AIO) Backup: 1.2.0

Same issue. `./occ backup:point:create --differential -v` output: ``` In PointService.php line 456: [OCA\Backup\Exceptions\ParentRestoringPointNotFoundException] cannot create differential. parent cannot be found Exception trace: at /var/www/html/custom_apps/backup/lib/Service/PointService.php:456 OCA\Backup\Service\PointService->initParent() at /var/www/html/custom_apps/backup/lib/Service/PointService.php:421 OCA\Backup\Service\PointService->addingRestoringData() at /var/www/html/custom_apps/backup/lib/Service/PointService.php:401...

I cannot reproduce this issue. Furthermore, by design it has nothing to do with the backup app, but only with the external storage app. You can control who has access...
