Estimating data change rates for VR

Hi!

Can anyone please come up with ideas on how to measure estimated data change rates when one is planning to implement VR (with / without SRM) for a particular Virtual Machine?

I know VR shows this info once I've set it up for a VM and configured a specific RPO, but can I do it in advance for my VM? Like using the vSCSI filter in "what-if" mode.

Snapshot and monitoring the delta size might be one possible solution however it involves some risks.

Monitoring VM write requests will skew the picture if the same block is overwritten multiple times during RPO.

Anything else? I'm sure this question has popped up in other heads as well Smiley Happy

Thanks in advance!

WBR
