Files being deleted, folder structure remains

Hi all,

We have been running NC at our company the last couple of years, and have around 200 users in our own datacenter.
It has mostly been running well with good performance, but lately we have been having some behaviour that i cant determine if its a user error or bug.
The bevaiour im seeing is that once in a while, all the files in a Group folder will be moved to the trash, but all the sub folders will remain, albeit empty. When checking logs, i can see the files being moved to the trash, but i cant determine what triggers the deletion action. I doubt that it is done by the user, since the folder structure remains, and i guess its pretty hard to go in to each folder to delete only the files by accident.

Has anyone else observed similar behaviour? Or have any ideas of how to troubleshoot this?

NC Version: 28.0.5
Ubuntu 22.04 LTS

Unfortunately you haven’t provided any information about the apps you’ve installed on your server, but it might be possible that you’ve installed the Retension app, which can be used to automatically delete files after some time.
