I'm performing a once-a-day registry backup using VSS and settings are to save at least "x" copies and delete copies older than "d" days. Registry Backup deletes the files in the old backup folders but doesn't appear to delete the folders themselves. Merely a nuisance but perhaps needs tweaking if it's not peculiar to my system.
