Error occurs when a backup operation is initiated on a Windows 2012 based Cluster Shared Volume.
The following events have occurred:
The backup operation fails with any one of the following storage errors, as indicated in the Failover Cluster Manager:
STATUS_IO_TIMEOUT
ERROR_TIMEOUT
STATUS_CLUSTER_CSV_AUTO_PAUSE_ERROR
During the backup operation, while a snapshot of the Cluster Shared Volume (CSV) is created, the virtual machine enters a paused state because the Ntfs.sys driver incorrectly reports the available space on the CSV. The CSV volume eventually goes offline because it does not resume from a paused state after an I/O delay issue or error occurs.
To resolve this issue, refer to the Microsoft KB article 2813630.
