Preparations

The following example uses single-server HANA 2.0 running on SUSE 11 SP4 for SAP to demonstrate how to use a custom script to freeze and unfreeze the HANA database in order to implement application-consistent backup.

Context

An enterprise purchases ECSs and installs HANA 2.0 on ECSs for saving business data. As data increases, crash-consistent backup cannot meet the RTO and RPO requirements and therefore application-consistent backup is needed.
