Difference between Storage Volume and Host Volume in EVA8400

Dear Friends,

I am bit confused with Storage volume and Host Volume. In the RSM Job Template there are different templates for Business copy templates for Storage volumes and Host Volumes.
Can u please anyone explain when to use the 1.Business copy templates for Storage volumes and 2.Business copy templates for Host Volumes

What is the diff. when replicate Storage volume vs host volume via Snapclone ?

Any help will be appreciated

Thanks
