Netbackup OST - Enterprise Vault Agent Implementation

I need some info on NetBackup OST and policy type set as Enterprise Vault.

I need to know if I can create a NBU 7.6 Enterprise vault policy, and then backup the data to and OST device and replicate the data to anoter OST device (DR)  with SLP.

1. Can you use SLP with Enterprise Vault Agent ?

2. Can you replicate the Data from one OST to another Via SLP's

3.Will the data be consistent  and can I bring up EV then in the DR environment with this data
