How to calculate ROC of a production site

  • I’d like to know how I can calculate the Rate Of Change of the protected site. I have a situation where a protected site is not replicating quick enough using Zerto and my network team say the WAN link between the protected and recovery sites is 100% utilised.

    I thus would like to upgrade the WAN link however I don’t know what the ROC is of the protected site in order to calculate how much bandwidth I should upgrade my WAN to?

    Can this be taken from the Zerto reports?


    About estimating WAN traffic, you can use the WAN Sizing tool of ZVM.

    Please use your myZerto account to access this link:


    Then, go to the tab of your ZVM version and search for “WAN Sizing” keyword on the page.
