Hyper V System Recovery

I need to setup a new server for SQL server and a web hosting purpose. The server may need 1-2 hyper v virtual machine running in the host.

I will install Symantec System Recovery Server Edition in the host server for preform regular backup and restore.

I have a question, if a user deleted a file in the hyper v virtual machine. Can I recover it through the Symantec System Recovery on the host?

If no, is that means I need to install 3 Symantec System Recovery Server Edition (one in the host, one in hyper v virtual machine and one in another hyper v virtual machine) in order to recover the hyper v virtual machine?

thank you.
