The virtual machine 'VM-name' requires snapshot consolidation.
Explanation
Snapshot consolidation is required when a snapshot is deleted but its associated disk is not committed back to the base disk. If consolidation is not completed, snapshot disks might grow and eventually fill the data store.
System action
The virtual machine backup continues.
User response
