V-79-57344-38264 - VMware backup fails with error: "0xe0009578 - Unable to copy the virtual machine disk using the VMware VixDiskLib"

Problem

Backup of a VMWare Virtual Machine (VM) fails with error:
V-79-57344-38264 - VMware Backup fails "0xe0009578 - Unable to copy the virtual machine disk using the VMware VixDiskLib"

A duplicate job of the backup set with this failure will also fail.

Error Message

Final error in Backup Job Log:
0xe0009578 - Unable to copy the virtual machine disk using the VMware VixDiskLib

The verify section of the Job Log reports: 
Data for VMVCB::\\<path to vmdk> is corrupt.

Cause

This issue seems caused by a misaligned disk.
One of the Virtual Machines disks was increased or expanded in size. 

Solution

WORKAROUND :

1. Increase the size of the VMDK reporting this issue by a few MBs or GBs which should realign the disk.
ideally increase the disk size into integer number size.
Additionally in some instances a shrinking of the volume from inside the virtual machine by (1 or 2 GBs) may resolve the issue.

OR
Attach a new disk (vmdk) and copy all data from old disk to newly attached disk. 
Give it the same drive letter after removing the old disk (vmdk)

2. Reboot the Virtual Machine.
3. Rerun a FULL job with verify enabled before attempting any incremental or differential jobs.
