When you use Site Recovery Manager to configure the protection for virtual machines, you reserve resources on the recovery site by creating placeholders. You map the resources of the protected virtual machines to resources on the recovery site.

When you add a virtual machine or template to a protection group, Site Recovery Manager creates a placeholder virtual machine at the recovery site.

You must create inventory mappings so that Site Recovery Manager can create placeholder virtual machines.

For every virtual machine in a protection group, Site Recovery Manager creates a placeholder virtual machine at the recovery site. You must identify a datastore on the recovery site in which Site Recovery Manager can store the placeholder virtual machines.

You configure datastore mappings to determine which datastores vSphere Replication uses to store replicated virtual machine disks and configuration files at the recovery site.
