Cause
Rapid Recovery agentless backups fail due to ESXi/VCenter fails to create snapshots for the virtual machine with "invalid snapshot configuration" message.
Commonly, when you see an invalid snapshot configuration, VMWare is no longer able to re-consolidate the disks.

Resolution
Workaround 1:
This is a VMWare issue that can be resolved by migrating the VM (VMDKs and the configuration files) to a new or any available datastore.
Workaround 2:
Remove the snapshot chain manually, and point the VM back to its original (underlying) *.vmdk and *flat.vmdk file.
