Roon says that it has backed up to a local shared directory on my QNAP. However I look in the directory and no files or folders have been updated for months.
There is a disconnect between the Find backups listing and the folder contents. The folder shows 4 subdirectories, which I assume are the Roon backups. “Find backups” shows 2 subdirectories. 1 is one of the 4 listed above. The other is a directory which isn’t in the QNAP Roon Backups folder. Tried doing a search for the folder and it wasn’t found. The other 3 folders in the directory aren’t shown.
I then went and renamed all of the shared backup folders to different names. Removed the automatic backup location. Restarted Roon. Went to specify the automatic backup folder. It still shows “Roon Backup” as a folder with the 2 subfolders even though it doesn’t exist and it was removed from both QNAP and Roon.
The folder which I can’t find unfortunately has no date in Roon’s “Find Backup” so I don’t know what it is.
I think your best solution is to create a new empty folder for your backups and do a manual backup. If that works, schedule a backup and see how that goes.
