VM client failing with a status 6/23 in the job details while attempting to use SAN or HOTADD transport. When the backup job runs it would fail almost immediately with errors shown below.

Client would backup via NBD transport and even after vMotion of VM to a different Datastore and ESX host the problem persisted.

Problem was caused by orphaned snapshot mount point and lock files on the  appliance or the backup / access host if NOT an appliance.


The files in the /tmp/vmware-root directory were deleted.

Once that was done the SAN or HOTADD transport backup worked.

The same files on a Windows Backup host reside in the C:\Windows\Temp\vmware-SYSTEM directory.

These files should / can be deleted when this backup is not active
