Description: The shadow copies of volume \\?\Volume{0cb23f5e-d66f-11dd-aa0c-cd6941b8c127} were aborted because the shadow copy storage volume was not present.
Resolution
The VSS Shadow Storage may need to be associated with each NTFS volume within the guest virtual machines. This can be done by performing a command similar to the one below for each volume in each virtual machine that supports the assignment of VSS Shadow Storage:
Example:
vssadmin add shadowstorage /for=c: /on=c:
(/for = Specifies the volume for which the shadow copy storage association is to be added.
/on = Specifies the volume to be used as storage for the volume that is defined in the /for parameter.)
Re-run the Hyper-V backup
(/for = Specifies the volume for which the shadow copy storage association is to be added.
/on = Specifies the volume to be used as storage for the volume that is defined in the /for parameter.)
Re-run the Hyper-V backup
