Hello I have windows server 2012 which is also a DC and has dfs running on it. I have set up server backup to perform a daily backup of the full server. The first two days this worked without any issues but since then I am getting a backup failed with"access is denied" error. In the event log there are various events for disk and ntfs ( warning 153 disk and error 137 ntfs) that seem to start the whole thing off. Have looked on forums and google and tried disabling antivirus, giving elevated permissions
to the system account etc but with no change in events so far. Any guidance would be appreciated. Thanks
