Challenge
The following error occurs during a task that utilizes the Microsoft VSS subsystem:
VSSControl: -2147467259 Backup job failed. Cannot create a shadow copy of the volumes containing writer's data. VSS asynchronous operation is not completed. Operation: [Shadow copies commit]. Code: [0x8004231f].
Of specific importance is the error code value, either: -2147467259 or 0x8004231f.
Cause
This error can be caused by:
insufficient disk space on one or more volumes of the machine that is being backed up. [Most Common cause]
Note: This can include the System Reserved Partition.
a defined shadow storage associations with a maximum size that is smaller than what is necessary to create the shadow copy
a volume larger than the maximum size Microsoft VSS supports (64TB).
Operation: [Shadow copies commit]. Code: [0x80042306]
Solution
Verify Sufficient Free Space
Within the VM guest OS that cannot be backed up or replicated, use the Disk Management utility (diskmgmt.msc) to view free space on each NTFS volume:
More Information
It is not necessary to enable shadow copies for shared folders. It is normal for “Next Run Time” to show "Disabled".
