Hi, I am using a Qnap TS231-P as data storage for my Nextcloud instance. I setup a volume which is connected via nfs to my Nextcloud server, this is working for years.
The last weeks users reported that files are missing randomly. I check and found that sometimes complete user folders are missing. It’s not that only files are missing, sometimes complete folders get lost. Yesterday my own folders were deleted, so I had to struggle recovering from an OneDrive Backup.
Is it known that the current Qnap firmware is having a bug? For me it looks like this problem comes when older snapshots must be deleted.
To help investigate the disappearing files, we highly recommend you enable Access Logs. These logs can be very useful for tracking down the potential causes.
Additionally, please try to observe if the missing files share any common characteristics, such as file size, location, or any other factors. This could provide crucial clues.
If these symptoms continue to appear, please feel free to open a support ticket with our Support Team for further assistance.
