I’m wondering how anyone approaches the following scenario:

We have an existing NetApp system in place (ONTAP 9.4), currently taking Snapshots of all the required volumes as per the required RPO objectives as defined.

The question is:

There is now a requirement to implement a DR site using Asynchronous Snapmirror, based on the current snapshots and rate of change, what is an estimated bandwidth requirement to meet X RPO.

What tools or options are available for completing such an exercise or the methodology

Thanks
