Backup not complete again

I may have a problem with your source folder path statement. Using an extensive path name for the source folder like Users/Myname/SourceFolder does get the Test Connection to pass but after a few days I find that I can get the same result without even having to specify a SourceFolder. When I run my backup job with an extensive path, the backup successfully executes but produces no output. It works exactly the same if I specify a non-existent SourceFolder; in fact, exactly the same without any SourceFolder being delineated at all! In the YouTube video by Mammouth Jerk, "How to set a Backup with a Netgear ReadyNAS step by step" he uses only the Share Folder name in the path statement, e.g., SourceFolder. When I attempt this, the Test Connection results in a Username or Password fail and the Backup job can't mount the source folder when executed. The ReadyNAS OS 6.2 manual states one should use the Browse/pull-down menu to select the source folder but for the OS 6.2.2 remote source settings, the pull-down menu is greyed out so the only way I can specify a source is to type it in. The pull-down menu for the local destination shares folder works as advertised. So I have been unable to get a Backup job to correctly execute (no output in the Destination folder) although I have no trouble using the ReadyCLOUD app interface to create a successful backup job. The only problem with the ReadyCLOUD app interface is that one can't specify a source folder below Users/Myname directory level (the My Documents / DOCUMENTS directory level). Currently I am refusing to completely reorganize my computer's file organizational structure having been at it since the days of DOS and having gotten use to it!!
