Volume Replicator (VVR) includes the following features:
Can be configured to work with any storage hardware supported by Veritas Volume Manager.
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.
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.
Supports different volume layouts on Primary and Secondary hosts. For example mirrored layout is supported on Primary hosts and non-mirrored layout is supported on Secondary hosts.
Provides the ability to validate data on the Secondary without application downtime or stopping replication.
Provides a configuration check utility, /etc/vx/diag.d/vvrcheck, that displays current replication status, detects and reports configuration anomalies, and creates statistics files that can be used by display tools.
