One or more iSCSI disks are configured in the virtual machine '%1'. Back up programs that use the Hyper-V VSS writer cannot back up iSCSI volumes that are configured through the guest operating system of a virtual machine. To avoid potential data loss, use another method to back up the data on the iSCSI disks. If you restore the data on this virtual machine, make sure to check the data of the iSCSI disk for integrity.
