I don't think it allows to replicate within a vcenter to the replicated VM.
instead enable FT on that VM to be available in the same vcenter,
Actually, we are running vSAN and have set FTT to 1. We also have a DR site and we'll be using SRM and VR to replicate the VMs to DR site. What I want is to have another copy of my critical VMs on local esxi datastore just incase anything happens to vSAN and DR.
Is that possible with FT? for FT don't we require a share datastore?
Okay I got it,
Please review the best practices from the below links and apart from replication, it is good to have a backup solution for your critical VMs.
Well, with vSphere replication you can only do one to one replication for a VM. One to many replication for a VM cannot be done.
