About Veritas Access episodic replication

The Veritas Access episodic replication solution provides high performance, scalable data replication and is ideal for use as a content distribution solution, and for use to create hot standby copies of important data sets.

Veritas Access episodic replication lets you asynchronously replicate a file system from one node in a source cluster to another node in a destination cluster at regularly timed intervals. This allows for content sharing, replication, and distribution.

The Veritas Access episodic replication functionality allows episodic replication with a minimum timed interval update of 15 minutes and no set maximum. Unlike many replication solutions, Veritas Access episodic replication also allows the destination file system to be online for reads while replication is active.

Major features of Veritas Access episodic replication include:

• Online access (read-only) to replicated data.

• Immediate read/write access to destination replicated data in the unlikely event that the source file system goes offline for a sustained period of time.

• Load balancing across replication links.

• Transport failover of episodic replication service from one node to another.

• Unlimited simultaneous episodic replication operations.

The Veritas Access episodic replication feature is designed to copy file systems only between Veritas Access clusters.

The Veritas Access episodic replication feature does not support user modifications to the target file system if episodic replication is configured.
