Create a Backup

Note: This option requires an SAP HANA, express edition Server + Applications installation.

1. Open SAP HANA Cockpit and log in using XSA_ADMIN.

2. Open your system database in the Resource Directory window.

3. Scroll down to the System DB Monitoring and Administration section and click Manage database backups under Administration.

   

4. On the bottom right of the page, click Create Backup.

   

5. Select your Backup Type and Destination Type. You may also change the Backup Prefix and Backup Destination. By default the values for Backup Prefix and Backup Destination are <date>_<time> and /usr/sap/<sid>/HDB90/backup/data/SYSTEMDB/.

   Click Back Up to create your backup.

   

6. A new page will open with a progress bar. Creating your backup will take a few minutes.

7. Once the backup is complete, a new page will show your successful backup. Two files are created: <backup_prefix>_databackup_0_1 and <backup_prefix>_databackup_1_1.

   

1. On SAP HANA Studio, log on to your SAP HANA, express edition installation.

2. Double-click the Backup icon

   

   .

3. If this is your first backup, under the Overview tab, click back up now. If this is not your first backup, click the Open Backup Wizard icon

   

   by Status of Currently Active Data Backup.

   

   The backup window opens.

4. Choose your Backup Type and Destination Type as necessary. By default, the values are Complete Data Backup and File.

   • Choose your Backup Destination and Backup Prefix. This will be where your files are stored and what they will be called. By default, the values are /usr/sap/<sid>/HDB<instance_number>/backup/data/SYSTEMDB and COMPLETE_DATA_BACKUP.

   • When you are finished, click Next >.

   

5. Review your backup settings and click Finish to begin creating your backup. Creating your backup will take a few minutes.

1. In SAP HANA Studio or another connected SQL command line, create a backup user and grant it backup permissions.

   Shell Copy

   CREATE USER backup_operator PASSWORD <password> NO FORCE_FIRST_PASSWORD_CHANGE;
   GRANT BACKUP OPERATOR to backup_operator;
   ALTER USER backup_operator DISABLE PASSWORD LIFETIME;

   This creates the user backup_operator with the given password and tells the system to not require a password change upon first login. It gives also gives backup_operator permission to make backups. You will be using this user to only create backups so logging in for each backup is not required. You only need to do this once.

2. Connect to your SAP HANA, express edition installation using a command line.

3. Log in as hxeadm.

   Shell Copy

   su -l hxeadm

4. Create the backup key.

   Execute the following command to create the user key backup.

   Shell Copy

   hdbuserstore -i SET backup <hostname>:3<instance_number>13 backup_operator

5. Create the file backup.sh.

   Shell Copy

   vi backup.sh

   Copy and paste the following code:

   Shell Copy

   ## defines backup prefix
   TIMESTAMP="$(date +\%F\_%H\%M)"
   BACKUP_PREFIX="SCHEDULED"
   BACKUP_PREFIX="$BACKUP_PREFIX"_"$TIMESTAMP"
   # TENANT="<tenant_database_name>"
   ## runs the backup sequence using the backup key
   hdbsql -U backup "backup data using file ('$BACKUP_PREFIX')"
   # hdbsql -U backup "backup data for $TENANT using file ('$BACKUP_PREFIX')"

   This script will be used to create your backups. If you need to backup more than one database (you have tenant databases, for example), use the commented sections as a template.

6. Give backup.sh run permission.

   Shell Copy

   chmod u+x backup.sh

7. Run backup.sh.

   Shell Copy

   <location_of_backup_script>/backup.sh

   Example:

   Code Copy

   /hana/shared/HXE/HDB90/backup.sh

   Wait while your backup is created.

8. (Optional) Check your backup repository to ensure your backup was created.

   Shell Copy

   ls /usr/sap/<sid>/HDB<instance_number>/backup/data/SYSTEMDB

   Example:

   Code Copy

   ls /usr/sap/HXE/HDB90/backup/data/SYSTEMDB

   A list of your backup files is displayed.
