- Log on to the Elastic Compute Service (ECS) instance on which the backup client is installed.
- Modify the
/usr/sap/<SID>/SYS/global/hdb/opt_backupfor the SAP HANA instances. This applies to the SAP HANA instances that you do not need to back up.
- Log on to the Hybrid Backup Recovery (HBR) console, and reinstall the backup client for the SAP HANA instance.
