Windows Sever Backup to SMB error "THe username not recognized by local computer"

Question

I have a Server 2012 machine that's in a workgroup so no AD involved.

When I tried to create a backup schedule all goes well until I try to authenticate it says that "the User name being used for accessing the remote share folder is not recognized by the local computer"

I believe this problem can be resolved if my server was a DC and the NAS was set to authenticate using AD. But I don't want/need this

Any work around this?

Is the backup initated by the Windows server, or is the backup job running on the NAS? &nbsp;Also, if the latter, is it the built-in web backup job or replicate?

I don't have Windows 12 but on for my Windows 2008 server&nbsp;my back up software&nbsp;worked&nbsp;when&nbsp;when there is a user with the same name and password on both the Windows server and on the NAS box.&nbsp; You can 1) create a backup service user on the server with a password that never expires and create the same user / password on the NAS; 2) add the name and password you are using on the Windows server as a NAS box; or 3) add the name / password that you log onto the NAS with&nbsp;as a user on the Windows server.&nbsp;&nbsp; &nbsp;&nbsp;Also the native Windows back up solution on my SBS2008 server wants a local drive to backup up to.&nbsp; I believe a mapped drive would be accepted.&nbsp;&nbsp;&nbsp;YMMV but hope this helps.

Not something I've tried (I use Acronis TrueImage, which has no problem backing up to the NAS). &nbsp;The faq here says you'll need AD though:&nbsp;http://kb.netgear.com/app/answers/detail/a_id/29754
&nbsp;
You could simply follow the guide (ignoring the AD requirement, but setting up a user account on the NAS that matches the username/password you use on the server). &nbsp;Then use that account on the last step - and see what happens. &nbsp;But I suspect that's basically what you did.
&nbsp;
Two other approaches that I think will work around the AD requirement: &nbsp;
-create an isci lun on the NAS for backup
-create a vhd on the NAS for backup
&nbsp;
Both are conceptually equivalent - you end up with an NTFS-formatted virtual disk attached to the server either way. vhd is windows technology, so it might work out better.
&nbsp;
Or of course use a different backup tool.&nbsp;
