Veritas File Replicator (VFR) includes the following features:
Supports reversible data transfer. The target of replication may become the source at runtime, with the former source system becoming a target.
Provides efficiency of data transfer when transferring shared extents, so that the data is not sent multiple times over the network.
Supports automatic recovery from the last good successfully replicated point in time image.
Periodically replicates changes. The interval is configurable by the user.
Supports deduplication to increase storage efficiency on the target system.
See the Veritas Storage Foundation and High Availability Solutions Replication Administrator's Guide for more information.
