how to vmware backup

hi all,

i need to configure vmware backup in tape.

i need to know best policy for vmware backup. overwrite protection period required to set.

i am using backup exec 2010 with service pack 4 + hotfix.

there are some policies already with backup exec. such as "Agent for vmware incremental 0001". i need to take vmware vmdk images.

will this policy work?
