Event ID 8249 is logged every 10 seconds when you try to recover files from a backup file by using Windows Server Backup in Windows Server 2012

Symptoms
Assume that you have File Server Resource Manager (FSRM) installed on a Windows Server 2012-based computer. When you try to recover some files from a backup file by using Windows Server Backup on the computer, the files are not recovered. Additionally, the following event is logged every 10 seconds during the recovery process: 

Log Name: Application
Source: SRMSVC
Event ID: 8249
Level: Warning
Description: File Server Resource Manager was unable to access a file or volume.
Details: \\?\Volume volume ID \System Volume Information\SRM\FciNrt.usn.altThe volume may be inaccessible for I/O operations or marked read-only. In case of a cluster volume, this may be a transient failure during failover.

Cause
This issue occurs because FSRM periodically tries to access a volume that is marked as "read-only" by Windows Server Backup. 

During the recovery process, Windows Server Backup mounts the Virtual Hard Disk (VHD) file that contains the backup as a read-only volume. Additionally, FSRM checks for new volumes on the system every 10 seconds. When FSRM finds the read-only volume and then tries to open and write to it, the operation is not successful. Therefore, event ID 8249 is logged every 10 seconds.
Resolution
This hotfix is also available at Microsoft Update Catalog.
