This is similar to post https://community.netgear.com/t5/Backing-up-to-your-ReadyNAS/Backup-Mac-to-ReadyNas/m-p/870820#M5014

The OP was able to at least pass Test Connection and was using SMBUp to override Apple's SMB implementation. One difference is that I am not trying to bypass Apple's SMB implementation and not using SMBUp or any third party tool. Is the Apple SMB implementation still a problem? 

Here's what I tried to do:

I AM able to do a TimeMachine backup from my MacBook (and I can connect to my ReadyNAS from Finder using CIFS and AFP). 

But since I want to backup a folder from my MacBook to my Readynas Duo v1 and am also using Windows laptops on my home network that access the same folder/subfolders/files, I'd prefer to backup using Remote: Windows/NAS (Timestamp) or another file protocol if that is possible. 

On the Mac:

I checked File Sharing on in the System Preferences -> Sharing, and added the folder (will call it Folder for this post) to be backed up in Shared Folders. Also ensured that my account name under Users has Read/Write access. Noted that "Computers on your local network can access your computer at: MyName-MacBook-Pro.local"

Also noted option - "Other users can access shared folders on this computer, and administrators all volumes, at “afp://myname-mbp” or “smb://myname-mbp”

On the ReadyNAS FrontView in Chrome:

When setting up the backup job using Remote: Windows/NAS Timestamp, I provide the following:

Host: the computer name that other computers on my local network can access -  MyName-MacBook-Pro.local

Path: Folder (this is the shared folder)

User name: myaccountname (my short account name)

Password: *****

When I hit Test Connection, I get the error message: "The page at ... says: Error connecting to //MyName-MacBook-Pro.local/Folder"

I tried changing the Host name to smb://myname-mbp and also tried changing Path to Users/myaccountname/Folder but get continue to get the Error connecting message. 

What is/are the problem(s) with my Backup Job settings?  The ReadyNAS Duo v1 manual says that Mac OS X uses the Windows/NAS protocol (although AFP is preferred).

A (related?) problem is that when I try to uncheck AFP (or CIFS) in FrontView - Services - Standard File Protocol, I get a browser error message - "Could not find the masquerade address in DNS.  Please check that the value has a DNS entry or enter a numeric IP address.", and the AFP/CIFS remains checked. Would appreciate help with this too!

Thanks!
