Veritas Volume Replicator (VVR) includes the following features:

• Replicates data for up to 32 remote locations over any IP network in a LAN or WAN environment.

• Performs replication of volume groups in asynchronous or synchronous modes, ensuring data integrity and consistency in both modes.

• Maintains write-order fidelity, which applies writes on the Secondary host in the same order that they were issued on the Primary host.

• Enables you to easily recover your application at the remote site.

• Provides effective bandwidth management using bandwidth throttling and multiple connections.

• Provides the ability to perform off-host processing such as Decision Support Systems (DSS) and backup, by enabling you to break off a consistent mirror or snapshot of the data volumes on the Secondary to use for these operations.

• Provides the command-line interface and the graphical user interface for online management of the VVR environment.

• Provides multiple methods to synchronize the data at the Secondary location with the data at the Primary location.

• Can be configured to work with any storage hardware supported by Veritas Volume Manager.

• Easily accommodates growth of application data and system configurations.

• Supports cross-platform replication, that is, the Primary and Secondary can have different operating systems.

• Supports volume-level replication of application or file system data, which includes support for all commercial database management systems, such as Oracle, DB2, Sybase, and Informix.

• Supports volume-level replication of data in a shared storage environment, for use with parallel applications, such as Oracle RAC (Real Application Cluster).

• Supports replication of VxVM volume sets, including ensuring consistency between the component volumes of the volume set on the Primary and on the Secondary.

• Supports replication in a PDC (Portable Data Container) environment.
