Async DR Protection Domain: A standard protection domain is a defined group of VMs that are backed up locally on a cluster and optionally replicated to one or more remote sites. This type of protection domain uses asynchronous data replication to create snapshots. Protection domain names must be unique across sites. A VM can be in at most one protection domain. A protection domain on a cluster is in one of two modes: Active: Manages live VMs; makes, replicates, and expires snapshots. Inactive: Receives snapshots from a remote cluster.
