Environment:
Windows Server 2012 R2 Essentials running in VirtualBox in a Windows 7 host. Networking is configured and works fine.
Background:
My only backup needs are to copy the contents of two folders to a NAS folder every day at 2 AM.
I configured a backup schedule in Windows Server Backup (wbadmin) to a network location which is hosted as a Samba share on a Synology NAS.
For authentication, I created a backup user which has the same username and password as a user on the Samba share, with permission to read and write the backup folder. I added this user to the Backup Operators group.
Problem:
When I try to run the Backup Once operation to test my backup, I get the following error message:
"Windows Backup cannot read the backup destination."
What I've tried:
I verified that the location is directly accessible in Windows by copying and pasting the address from the Windows Server Backup destination into explorer. Providing the backup user credentials opened the location and creating/reading files worked fine.
Adding the backup user to the Administrators group did not have an effect.
Update 2014-02-18
I checked the backup destination and was surprised to find that the scheduled backup actually completes successfully. However, Backup Once always results in the above error message.
