Back up SAP HANA databases

Contributors netapp-soumikd

If a resource is not yet part of any resource group, you can back up the resource from the Resources page.

What you will need

  • You must have created a backup policy.

  • If you want to back up a resource that has a SnapMirror relationship with a secondary storage, the ONTAP role assigned to the storage user should include the “snapmirror all” privilege. However, if you are using the “vsadmin” role, then the “snapmirror all” privilege is not required.

  • For Snapshot copy based backup operation, ensure that all the tenant databases are valid and active.

  • To create SAP HANA system replication backups, it is recommended to add all the resources of the SAP HANA system into one resource group. This ensures a seamless backup during takeover-failback mode.

  • If you want to create a file-based backup when one or more tenant databases are down, set the ALLOW_FILE_BASED_BACKUP_IFINACTIVE_TENANTS_PRESENT parameter to YES in the HANA properties file using Set-SmConfigSettings cmdlet.

    The information regarding the parameters that can be used with the cmdlet and their descriptions can be obtained by running Get-Help command_name. Alternatively, you can also refer to the SnapCenter Software Cmdlet Reference Guide

  4. In the Resource page, select Use custom name format for Snapshot copy, and then enter a custom name format that you want to use for the Snapshot copy name.

      Disable WAFL Sync

      Select this to avoid forcing a WAFL consistency point.

    • Click the Scripts arrow to run pre and post commands for quiesce, Snapshot copy, and unquiesce operations.

  11. Monitor the operation progress by clicking Monitor > Jobs.

    • In MetroCluster configurations, SnapCenter might not be able to detect a protection relationship after a failover.

    • If you are backing up application data on VMDKs and the Java heap size for the SnapCenter Plug-in for VMware vSphere is not large enough, the backup might fail.

      To increase the Java heap size, locate the script file /opt/netapp/init_scripts/scvservice. In that script, the do_start method command starts the SnapCenter VMware plug-in service. Update that command to the following: Java -jar -Xmx8192M -Xms4096M
