Event ID 51

Hello,

I see on several 2012R2 servers between 5 - 8 warning events ID 51 "An error was detected on device \Harddisk1\DRxyz during a paging operation" (source: disk, protocoll name: system) in the beginning of a backup operation with Windows Server Backup. The backup destination is a NAS. Should we do something about these warnings?

Regards

Hi Ueli,

There is an article which specifically explained Error 51:

http://support.microsoft.com/kb/244780

As the article said, sometimes warning will be logged when a failure occurs but it may not be an issue such as insert a DVD into a writable drive.

Please just monitor your Windows Server Backup schedule. If it could be finished correctly, you can safely ignore the warning.  If any else error occurs please just post back and we can continue discuss.
