Failure creating datastore lock, invalid data store type for VM (4043025)

Backups to a VSAN or a VVOL are failing after upgrading vCenter to 6.7U1 with the following error:

•  Failure creating datastore lock, invalid data store type for VM:  vm-xxxx DiskInfo: VMFS=False NAS=False

The VMware API version has also been updated in the vCenter service after the upgrade to VMware 6.7U1. When upgrading the hosts, the VSAN on-disk version is automatically upgraded to version 7. 

This is being fixed as a part of the next release, however, there's a hotfix available for this issue. Please contact customer support to receive it. 

Currently, there is no workaround available.
