Are you running more than one backup program?
</div>

<div>
This server is configured to run &quot;LogMeIn Backup&quot; and &quot;windows server backup&quot; on a schedule.
</div>

<div>
Good idea I will disable the LogMeIn Services. and run a manual backup of windows back-up over the weekend.
</div>

<div>
disabling LMI and rerunning win backup worked 
thanks

Win server 2012R2 - server backup - failed

Windows Server 2012 is the server version of Windows 8 and the successor to Windows Server 2008 R2. Windows Server 2012 is the first version of Windows Server to have no support for Itanium-based computers since Windows NT 4.0. Windows Server 2012, now in its second release (Windows Server 2012 Release 2) includes Foundation, Essentials, Standard and Datacenter, and does not support IA-32 or IA-64 processors.

Windows Server 2012

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.
