    Logged in as administrator
    Going through Administrative Tools -> Windows Server Backup -> Backup Schedule
    Setting up a new remote backup on a different server (requiring different login credentials to save to that location if it matters)

    Everything goes through until I hit Finish on the Confirmation page, then after a few moments it gives me this:

    Error:
    "You must be a member of the local Administrators or Backup Operators groups to schedule a backup."

    It does let me run the Backup Once through Windows Server Backup to the same location, but not through Backup Schedule.

    Hi,

    To configure scheduled backup to network location, there is a restriction in Windows Server Backup that the user configuring the backup must be a valid user on the local machine (where backup source is) and the same user should have write access to the network share. To overcome the scheduling issue, would suggest to add the user having access to the network share as a BackupOperator on the backup source machine.

    Well, that seems to fix it, but the restriction seems silly when there is a popup asking for network login credentials (and the error is not in any way helpful).

    Thanks

    I too was facing this error when trying to create a scheduled backup on a Windows 2008 R2 server instance for Exchange 2010. Abhinav indeed provided the answer to my problem. Only because it was still a bit cryptic, I will try to clarify the solution for others Googling this topic.

    What I did: create a scheduled backup using Windows Server Backup for Exchange 2010 to a network share with a specific backup account from my Active Directory

    The error I got: You must be a member of the local Administrators or Backup Operators groups to schedule a backup

    The solution: Add the backup user account from Active Directory to the Backup Operators group locally on the machine using the server manager/Configuration/Local Users and Groups/Groups. I already had added the Active Directory group Backup Ops in which this backup account resides, but that did not work. You need to add the backup account directly to the local Backup Operators group . Also make sure the backup user account has access to the network share to which you want to perform the backup. These rights may be set through the Active Directory group in which you placed the backup user account and this does not (though it may) be the backup user account directly.

    The user name being used for accessing the remote share folder is not recognized by the local computer

    How is this done on a domain controller? When I try to add the local account it says "This snap-in cannot be used on a domain controller. Domain accounts are managed with the Active Directory Users and Computers snap-in." But as far as I know you can't create a local account using AD UC.

    So if I can't add a local account to the DC, then how can I setup a backup schedule with Windows Server Backup that saves to a network share?

    UPDATE: This doc applies to Server 2008 but seems like it is still true for Server 2012.

    Found my answer: 

    The following conditions are requirements for scheduling daily domain controller backups:

    • The destination volume for the backup must be on a separate hard disk from the source volumes. You cannot perform a scheduled backup to a network shared folder.

    • The external storage device for the backup must be connected to the domain controller that you are backing up.

    Couldn't find Local Users and Groups in Server Manager, but if you go to Winkey+X/Computer Management (or Run lusrmgr.msc) on the source machine, you'll find Local Users and Groups. This fixed it for me! You'd think the error would be more specific :P
    • Edited by VanillaDeath Friday, April 26, 2019 11:59 AM added lusrmgr.msc as another option

    Thank you thank you thank you @VanillaDeath. 

    I spent nearly half an hour banging my head against this issue when I should have been sleeping.

    I had the backup user in the Domain Backup Operators Group and it worked fine on the Primary Domain Controller, but Windows Server Backup on an application server on the same domain kept throwing up this stupid message saying

    "windows backup cannot schedule a backup because the user credentials provided are not a member of the local administrators or backup operators group".

    In hindsight, the message is actually clear. It clearly says "local" but that's easy to miss after a long day way past bed time.

    Added the user to the local backup operators group using lusrmgr.msc as suggested and it worked.

    I suppose it makes sense from a security perspective, but then again if a bad actor has access to one of your machines, then you're kinda in trouble already.
