Hello @Kavya and thanks for the post!

Can you clarify what you mean by DR?  Are you creating an offsite Aux Copy, or are you talking about the backups of the Commserve database?

@Kavya Are you a new customer to Commvault looking to configure backups for the first time in need of understanding sizing, plans, etc or are you specifically asking about plans themselves?

@Kavya , it sounds like you are looking for some architecture setup/advice.

If the docs are not providing what you need, I would reach out to your Account Rep who can advise with special tools.
