description SAP HANA System Replication Overview

SAP HANA System Replication provides continuous data mirroring from a primary SAP HANA database to secondary systems. This synchronous replication ensures near real-time availability and facilitates rapid failover for business continuity. It’s particularly useful for organizations requiring high availability and disaster recovery solutions, often integrated with platforms like Zerto. The technology supports in-memory databases and is designed for IT professionals managing critical SAP HANA environments.

help SAP HANA System Replication FAQ

What is SAP HANA System Replication used for?

SAP HANA System Replication is an essential disaster recovery feature used to synchronously copy the in-memory data from a primary HANA database to a secondary system. This ensures near real-time failover and business continuity in the event of a primary system outage.

What is the difference between synchronous and async HANA replication?

In synchronous mode, the primary HANA system waits for confirmation from the secondary system before committing data, ensuring zero data loss. In asynchronous mode, the primary system does not wait, which reduces network latency but risks minor data loss during an abrupt disaster.

How long does SAP HANA System Replication takeover take?

The actual takeover process in a properly configured SAP HANA replication setup typically completes in a matter of minutes. This rapid, near real-time failover capability is exactly why it is heavily integrated into enterprise disaster recovery solutions.

Is SAP HANA System Replication included in the base license?

Yes, the core HANA System Replication feature is natively included in the standard SAP HANA enterprise database license. However, setting up multi-tier replication topologies or utilizing automated high-availability management tools may require additional configurations.
