This thread has been quiet for four weeks but the last two posters raised a very legitimate question:
You have told Roon users that the Roon backup program is working just fine and that backups can be successfully restored from folders that do not show any content in Finder or in Roon. Instead, the backups are hidden in these folders. Unless you are using Terminal, there is not way to “see” the backups in these folders. This definitely seems like a bug to me – users should be able to see each and every backup that is in their folders, shouldn’t they? Why hasn’t this bug been addressed? Why haven’t these questions been answered? I, and others who are wondering if Roon’s backup feature is really working as intended, would like some answers.
