Creating Database Backups

Creating Database Backups

Use the HANA studio management tool or command-line interface (CLI) to create backups for the two HANA servers.

  1. Log in a SAP HANA server (HW00001 in this example) as the root user and go to the /usr/sap/hdbclient installation directory.
  2. Run the backup command ./hdbsql -i 00 -u system -p -n localhost:30015 <SYTEM password> "BACKUP DATA USING FILE ('backup')" to create a database backup. If the following information is displayed, the database backup is created:

    HW00001:/ cd /usr/sap/hdbclient
    HW00001:/usr/sap/hdbclient # ./hdbsql -i 00 -u system -p Huawei_123 -n localhost:30015 "BACKUP DATA USING FILE ('backup')"
    0 rows affected (overall time 22.108163 sec; server time 22.107311 sec)
    NOTE:

    Before you run the backup command, ensure that the database is running in primary mode. The database is supposed not to be registered with another database. Otherwise, the backup command fails.

  3. If the database version is HANA2.0 or multiple_containers,backup SYSEMDB and tenantDB is necessary, Run following command(00 is the instance ,S00 is the SID):

    ./hdbsql -i 00 -u SYSTEM -p Huawei123 -n localhost:30013 "backup data for S00 using file ('COMPLETE_DATA_BACKUP')"
    ./hdbsql -i 00 -u SYSTEM -p Huawei123 -n localhost:30013 "backup data using file ('COMPLETE_DATA_BACKUP')"

  4. Log in to the other SAP HANA server as the root user and create the database backup in the same way.
