I can confirm the very low speed of replication with new versions.
I had a long running supportcase with no real sucess. I've got a new release ( 18.104.22.168029), now Hyper-V is working as expected.
But at Vmware the speed is still extreme low.
From support stuff, I also only get the "bottlneck" link, but this dosn't help at all!
Did you had any sucess?
Thanks for your feedbak

Usually, the customer adds the AWS access and secret access keys to the NAKIVO inventory that allows accessing the AWS server instance. We are not sure if Cloudways provides the access to API. So in your case, we can suggest backing up your web server as Physical Linux server. It will be supported in v9.1. The Windows physical server is supported starting from v9.0.
