Backup and Restoration

The SAP S/4HANA backup consists of two parts. One is the backup and restoration of disk snapshots and related file directories in SAP S/4HANA ASCS instance. The other is the backup and restoration of the SAP HANA database. The details are as follows:

  • SAP S/4HANA ASCS backup and restoration

    Prepare backup policies and regularly create snapshots for or back up disks of the ASCS instance. Ensure that the file directory (which is /usr/sap/<SID>/SYS/profile by default) containing Kernel and profile files on ASCS instance are covered by the backup policies. This is because these files contain configurations of Kernel, Start profile, Default profile, and Instance profile. When an AZ is faulty, you can use backup files or snapshots to restore the SAP S/4HANA system using VBS in the standby AZ.

    To implement DR restoration, you need to install SAP S/4HANA in the other AZ and use the backup directory to overwrite files in the original directory to restore the system. Then, restore the disks using disk backups through VBS.

  • SAP HANA database backup and restoration:

    The HANA system or storage replication function is used to ensure HA and remote DR and restoration for SAP HANA databases. For more SAP HANA information, see the section Backup and Restoration in the SAP HANA User Guide (Single-Node Deployment) and SAP HANA User Guide (Cluster Deployment). For details about HA and DR of SAP HANA data (including data and log volumes), see SAP HANA Database Backup and Recovery.

  • For details about how to back up and restore EVS, see sections Data Backup Using a Backup Policy and Data Restoration Using a VBS Backup in the Volume Backup Service User Guide.
