About Veritas Access sync replication
The Veritas Access sync replication solution provides high performance, robustness, ease of use, and synchronous replication capability which is designed to contribute to an effective disaster recovery plan.
Veritas Access sync replication lets you synchronously replicate volumes from one node in the source cluster to another node in the destination cluster. The synchronous replication enables you to maintain a consistent copy of application data at one remote location. It replicates the application writes on the volumes at the source location to a remote location across any distance.
If a disaster occurs at the source location, you can use the copy of the application data at the remote location and restart the application at the remote location. The host at the source location on which the application is running is known as the primary host and the host at the target location is known as the secondary host. The volumes on the primary host must be synchronized initially with the volumes on the secondary host.
Major features of Veritas Access sync replication include:
Performs replication of volumes in synchronous mode, ensuring data integrity and consistency.
Maintains write-order fidelity, which applies writes on the secondary host in the same order that they were issued on the primary host.
Enables easy recovery of the application at the remote site.
Provides both command-line interface (CLISH) and the graphical user interface (GUI) for online management of the synchronous replication.
See the sync(1) manual page for more information.
