Hi @David_Weinberg,
So we can better assist you, please provide a brief description of your current setup using this link as a guide.
Make sure to describe your network configuration/topology, including any networking hardware currently in use, so we can have a clear understanding of how your devices are communicating.
Just to verify here, if you do a Backup Now this works for this path, but scheduling a backup to this path doesn’t work?
If you were to select just the top level folder does it allow you to use that path?
