Manual failover requires continuous monitoring and could lead to higher recovery times. Takeover can be performed using SAP HANA Studio or the command line. If the primary SAP HANA system fails, the system administrator must perform a manual takeover.

Full Sync mode stops the surviving node if either node is down, so failover with SUSE HAE is not possible.
The focus of this reference architecture guide is SAP HANA System Replication. Data can be constantly pre-loaded in the memory of the secondary system to minimize the recovery time objective (RTO).

To provide fault recovery SAP HANA software includes a watchdog function, that automatically restarts configured services (index server, name server, and so on) in case of their failure. This should happen without any data loss (zero RPO) and in very short recovery time (low RTO). This requires that these systems can make faster recovery after system component failure (High Availability) or after a disaster (Disaster Recovery). SAP HANA database runs mission critical applications and it is important that these systems remain available to users always.
