Running a Hyper-V GRT backup to disk. I have three SQL servers but only one failed with the above error. The one that failed is our main SQL server and is always online. Other forums suggest unchecking the setting "Exclude virtual machines that must be put in a saved state to back up." If that were the case, wouldn't all the SQL servers fail since they were all setup the same? Any help would be appreciated.
If this still an issue can you please send me the system configuration of the hyper-V guest machine.
*Also, check if you have any dynamic disk configured on the guest machine, if yes those disk needs to be converted to basic disk because snapshots (VSS snapshot) will not work with dynamic disks.
*The VM guest needs to have Integration Services installed, enabled, and running (COM System Application Service, Distributed Transaction Coordinator Service, and Volume Shadow Copy Service). Also review the VM settings in Hyper-V, the 'backup' option needs to be checked.
