a full clone just copies the WHOLE vm to another place. A linked clone is a reference to the original vm files, where just the disk changes are written to a new location. Thus a full clone takes the full disk of the original vm at clone time. The disk space will grow for a linked clone. To my experience, there is no performance difference between a linked and a full clone.

Hi,

vmware states this in a whitepaper.

http://www.vmware.com/pdf/WS6_Performance_Tuning_and_Benchmarking.pdf

"NOTE If you will be using clones, remember that linked clones do not perform as well as full clones. Therefore, when creating a clone, make sure to choose From current state, then Create a full clone.

Avoid running virtual machines from snapshots or linked clones."


However, I really did not see any difference between a linked and a full clone. Maybe it's a matter of the use case for the vm.

I believe that it all depends to the modifications you are doing and how you manage Vms. If you accidentally delete a Vm's hard disc, the linked clone will be useless.

I personally do a full clone before I perform a series of steps such as promoting to a DC,installing exchange...

You might also want to do full clones if you want to compare two different approaches
