protected machine
A protected machine—sometimes called an "agent"— is a physical computer or virtual machine that is protected
in the Rapid Recovery Core. Backup data is transmitted from the protected machine to the repository specified in
the Core using a predefined protection interval. The base image transmits all data to a recovery point (including
the operating system, applications, and settings). Each subsequent incremental snapshot commits only the
changed blocks on the specified disk volumes of the protected machine. Software-based protected machines
have the Rapid Recovery Agent software installed. Some virtual machines can also be protected agentlessly, with
some limitations.

quorum
For a failover cluster, the number of elements that must be online for a given cluster to continue running. The
elements relevant in this context are cluster nodes. This term can also refer to the quorum-capable resource
selected to maintain the configuration data necessary to recover the cluster. This data contains details of all of the
changes that have been applied to the cluster database. The quorum resource is generally accessible to other
cluster resources so that any cluster node has access to the most recent database changes. By default there is
only one quorum resource per server cluster. A particular quorum configuration (settings for a failover cluster)
determines the point at which too many failures stop the cluster from running.

recovery points
Recovery points are a collection of snapshots of various disk volumes. For example, C:, D:, and E:.

recovery points-only machine
A recovery points-only machine is the representation on the Core of recovery points from a machine that was
previously protected on the Core, and since removed. If you remove replication but retain the recovery points,
this also results in a recovery points-only machine. Information can be viewed and recovered at a file level. You
cannot use a recovery points-only machine to perform BMR or to restore full volumes, nor can you add more data
to a recovery points-only machine.
