vmware-cmd createsnapshot command creates snapshot of a VM

The vcbMounter utility creates a quiesced snapshot of the virtual machine and exports
the snapshot into a set of files, which can be later used to restore the virtual machine.
To back up the set of files, you can use any filebased thirdparty backup software

Doesn't vmware-cmd snapshot create a quiesced snapshot?  To my recollection it does.  Thanks for you help.

To the best of my recolection kumarnirmal is correct.
the vmware-cmd createsnapshot command creates a crash consistent snapshot.
vcbMounter quiesces the guest disk before snapshot creation.
Of course vcbMounter is a Windows only tool. Actuall I'm sure I read support for creating snapshots directly via the host is limited and not encoraged.
Anyway VCB will take care of this for you..
Here's an example
vcbMounter.exe -h VC_Hostname -u domain\UserID -p password -a name:Guest_Displayname_in_VC -r Full_Path_to_Destination -t fullvm -M
