VMware Live Site Recovery can use vSphere Replication to replicate data to servers at the recovery site.
You deploy the vSphere Replication appliance and configure vSphere Replication on virtual machines independently of VMware Live Site Recovery. See the vSphere Replication documentation at https://docs.vmware.com/en/vSphere-Replication/index.html for information about deploying and configuring vSphere Replication.
vSphere Replication does not require storage arrays. The vSphere Replication storage replication source and target can be any storage device, including, but not limited to, storage arrays.
You can configure vSphere Replication to regularly create and retain snapshots of protected virtual machines on the recovery site. Taking multiple point-in-time (PIT) snapshots of virtual machines allows you to retain more than one replica of a virtual machine on the recovery site. Each snapshot reflects the state of the virtual machine at a certain point in time. You can select which snapshot to recover when you use vSphere Replication to perform a recovery.
If you are using vSphere Replication and VMware Live Site Recovery and perform reprotect on a replication without enhanced capabilities, the replication will be automatically converted to enhanced replication, if the enhanced setup is supported by both sites.
