Enterprise Vault backup

Hi

    I need to backup Enterprise vault ( mail server & file server ) in a cluster way components of EV distributed on different cluster machines

-  we have 2 SQL servers clustered

- 2 file servers clustered

- 2 mail server clustered  (exchange)

netbackup server 7.5 and EV 10

Do any one have a simple doc to implement this project

Thanks in advance
