Try uninstalling VMware Tools, (reboot server) and re-installing VMware Tools in the Virtual Machine.

You can confirm if your VM has this issue, but Select Snapshot Manager, Select Take Snapshot, and Creating a Manual Snapshot, By Ticking and Selecting Quiece VM, but Untick Memory.

Please see screenshot

We've tried the suggested solution and there's no problem doing a manual snapshot.

Creating snapshot from the VSphere is fine.
The problem is encountered during the VCB using the command below:  

C:\Program Files\tivoli\TSM\baclient>dsmc backup vm -vmlist=servername -vmbackuptype=FULLVM

This is the error:

[2011-09-22 10:25:11.421 'vcbMounter' 4012 error] Error: Other error encountered
: Snapshot creation failed: Could not quiesce file system.

Full solution is to select "This feature will not be available" for "Volume Shadow Copy Services Support" under "VMware Device Drivers"
