The issue you are facing:

Is this the first time you’ve seen this error? (Y/N): Y

I had to restore an old backup of my Nextcloud. After that a few files were missing. To get the files back I used the NextcloudPi file scan. But now the files were shown in the wrong folder. The file which was located e.g. in folder /Picture/Event1 is now shown in /Exchange/Data2023.
Is there a simple way to resolve the issue? I don’t need meta information back, I’d only get the data back.
Thanks!

The function occ files:scan --all scans the linux directories and give your database e.g. MariaDB the informations where the files are stored. I think the correct storage location is /Exchange/Data2023 and not /Picture/Event. Look in the linux filesystem, move the files to the correct place and re-run the scan-command. Also you can move the files in the Nextcloud GUI by user.

Maybe all is a backup/restore issue. Review your backup/restore process.

I checked the filesystem. Inside the filesystem it is correct. After a long further investigation I found the issue:

Is there any solution so far?

User two will see the thumbnail from user 1’s photo even though user 2 has no permission to user 1’s files, although when clicking on it it will open the correct photo.

Unfortunately I can not test the bug. But if this is true, then someone from the security group should take a look. Maybe someone is reading along.
