Automatic Recovery of SAP HANA ECSs

The public cloud provides automatic recovery by default to restart ECSs through cold migration, ensuring high availability and dynamic ECS migration.

You can enable automatic recovery during or after ECS creation.
An ECS can be automatically recovered only if the host on which it is deployed becomes faulty. This function does not take effect if the fault is caused by the ECS itself.
An ECS can be automatically recovered only once within 12 hours if the host on which it is deployed becomes faulty.
ECS automatic recovery may fail in the following scenarios:
- Many hosts in the system are faulty.
- The host to which the ECS services are migrated does not have sufficient temporary capacity.

The public cloud provides the automatic recovery capability for ECSs with easy configuration and no extra cost.

It is recommended to use the automatic recovery capability of ECSs in the SAP non-production environment.
