23 Managing application replicas
This chapter describes how to manage application replicas using Replication Manager.
About application replicas
An application replica is a snapshot of an application server that is saved to a series of secondary
volumes on an immediate or scheduled basis. As with copy pair management, the creation and
management of application replicas is organized around tasks and storage assets. Replication Manager
is used to create, manage, and (manually) restore replicas.
The following table lists the copy types that can be used for management of application replicas.

Managing generations (replica rotation)
Application Agent can manage multiple secondary volumes for a single primary volume. In these
cases, the secondary volumes are referred to as generations (or generational backups).
Normally, Replication Manager automatically determines which secondary volumes to use for the
backup destinations. In this way, the volumes where replicas are stored are automatically rotated in
the same way that backup tapes are created and later re-used. This (default) behavior is determined
by the Target Generation option located on the 2. Setup Options page of the Create Replica Wizard.
