How to backup a particular volume using Virtual Disk API ?

Hi,

I am trying to write a backup & restore application for VMWare virtual machines.

I am able to read entire content of the vmdk file using VixDiskLib_Read function, but i want backup a specific volume in this disk.

How to do that ? Also i want to know how to read only occupied memory(disk) and eliminate blocks of free space ?

Thanks & Regards,
