About VVR
The VVR snapshot method (for UNIX clients only) relies on the Veritas Volume Replicator, which is a licensed component of VxVM. The Volume Replicator maintains a consistent copy of data at a remote site. Volume Replicator is described in the Veritas Volume Replicator Administrator's Guide.
The VVR snapshot method can be used for alternate client backups only, in the data replication configuration.
See Alternate client backup through data replication example (UNIX only).
VVR makes use of the VxVM remote replication feature. The backup processing is done by the alternate client at the replication site, not by the primary host or client.
VVR supports VxVM instant snapshots.
