Thanks for the update! I haven’t had a reason to check my backup destination folder for a couple months so hadn’t even realized there was an issue!!

Yeah... my cron job started reporting errors when it ran out of backups to delete. Otherwise I may have never found out. If/When I get some time, there will likely be a future iteration that includes notification should backup retrieval fail. Though that may require re-writing it in python.
