Best Practice for SAP to Implement RM and Snapview?

I have a question from our TC in Indonesia related to SAP, could you advice me please?

Our customer (Tudung) has purchased Snapview including RM & also DD.

Then, DD has design / setup for doing "backup" every hour for SAP data only.

In term of snap, is there any best practice from EMC for SAP data, how to implement RM & Snapview ?

Basically Tudung required "fast recover" if there is a failure in their SAP data.

What is the the best scenario design for this request ? Fyi the RPO at least 2 hours.

- Do they need configure Snap every hour for all of DB, CI, log & archive log ?

- Do they need configure Clone & Snap ?

- In which configuration, the SAP data will be guaranteed consistent when it recovered from snap/clone data.

Pls advice which type of data should be snap or which type of data should be clone and how about the schedule of snap/clone for each type of data.

Fyi,

All of SAP data running in VMWare, Windows Server 2008 & Oracle as DB

Thank you kindly.
