There are 10 topic areas and you can expect about 8 questions for each topic.
- High Availability and Disaster Tolerance (this blog)
- Database Administration Tools and Tasks
- Monitoring and Troubleshooting
- Backup and Recovery
- Security

In this blog, I will discuss the High Availability and Disaster Tolerance topic.
On the SAP Training website for C_HANATEC_13, the exam objective for this topic is stated:
Design a strategy for high availability and disaster recovery,
explain the high availability and system replication features
of SAP HANA.
Study Material
The exam guide states that the study material for this topic comes from training
However, I have not been able to find much material on HA/DR or system replication in this training but expect this to be added for the next release.
You can download the index of the guide with the unit and lesson objectives from the SAP Training website.
There is an openSAP course on HA/DR
There is also a TechEd recording available from May Chen, SAP HANA product management

What’s New?
The focus will be on the new SAP HANA 2.0 features, so if you are new to this version you might be interested to view the What’s New videos first:

Note that C_HANATEC_13 covers SAP HANA 2.0 SPS 00 only. C_HANATEC_14 will cover SPS 02.
High Availability
For a good introduction on the topic, see
- Introduction: High Availability for SAP HANA (March 2017, Update for SPS 00)
This whitepaper will help you get familiar with RPO and RTO, and the different HA/DR options available for SAP HANA.
Backup and recovery is part of HA but for the exam, it is a separate topic area, see
You will also find several blogs on this topic on the SAP HANA Community, e.g.
- Enterprise Readiness with SAP HANA – Host Auto-failover, System Replication, Storage Replication
- SAP HANA High Availability and Disaster Recovery Series #1

System Replication
When system replication was just introduced, we did a whole series on this topic. Here is the playlist
The two most important videos are embedded below.
For the configuration, SAP HANA studio was used. For SAP HANA 2.0, you would use cockpit. The interface is less relevant, however, as the actual actions are performed by hdbnsutil.
For cockpit, see below Active/Active Read-Enabled.
