Getting Started
Storage Mirroring flexibility allows you to create different types of connections. For this evaluation, you can protect your
entire server, or you can protect specific data on your server.
 Providing disaster recovery for an entire server—If you are using the Storage Mirroring Server Recovery Option add-on,
you can protect the entire server, including your data and the server’s system state, which is the server’s configured
operating system and applications. Using the Management Console Connection Wizard, Server Recovery Option
automatically creates a replication set for you, selecting all of the data and system state data on the source. In the event
the source fails, you can recover the entire server, including the system state, to another machine. This connection type
is a disaster recovery solution only. See
Evaluating Disaster Recovery for an Entire Server on page 5-1 for instructions on
evaluating this type of connection.
 Providing high availability for an entire server—If you are using the Storage Mirroring Full-Server Failover feature, you
can protect the entire server, including your data and the server’s system state, which is the server’s configured operating
system and applications. Using the Full-Server Failover Manager, Full-Server Failover automatically creates a replication
set for you, selecting all of the data and system state data on the source. Additionally, Full-Server Failover automatically
establishes failover monitoring, providing high availability for the source. In the event the source fails, the target can
become the source after a reboot. See
Evaluating High Availability for an Entire Server on page 6-1 for instructions on
evaluating this type of connection.
 Protecting specific data—To protect specific data, you identify the data on the source to be included in the replication
set. The connection sends that data to the target. If the event the source fails, the replication set data will be available on
the target. By itself, this connection type provides disaster recovery. You can also configure failover to provide high
availability for your data. See
Evaluating Disaster Recovery or High Availability for Specific Data on page 7-1 for instructions
on evaluating this type of connection.
