Contributors netapp-soumikd

A resource group is the container to which you must add resources that you want to back up and protect. A resource group enables you to back up all the data that is associated with a given application simultaneously. A resource group is required for any data protection job. You must also attach one or more policies to the resource group to define the type of data protection job that you want to perform.

About this task

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.

Steps

  1. In the left navigation pane, click Resources, and then select the appropriate plug-in from the list.

  2. In the Resources page, click New Resource Group.

  3. In the Name page, perform the following actions:

    For this field…​ Do this…​

    Name

    Enter a name for the resource group.

    Note The resource group name should not exceed 250 characters.

    Tags

    Enter one or more labels that will help you later search for the resource group.

    For example, if you add HR as a tag to multiple resource groups, you can later find all resource groups associated with the HR tag.

    Use custom name format for Snapshot copy

    Select this check box, and enter a custom name format that you want to use for the Snapshot copy name.

    For example, customtext_resource group_policy_hostname or resource group_hostname. By default, a timestamp is appended to the Snapshot copy name.

  4. In the Resources page, select a host name from the Host drop-down list and resource type from the Resource Type drop-down list.

    This helps to filter information on the screen.

  5. Select the resources from the Available Resources section, and then click the right arrow to move them to the Selected Resources section.

  6. In the Application Settings page, do the following:

    1. Click the Backups arrow to set additional backup options:

      Enable consistency group backup and perform the following tasks:

      For this field…​ Do this…​

      Afford time to wait for Consistency Group Snapshot operation to complete

      Select Urgent, Medium, or Relaxed to specify the wait time for Snapshot copy operation to complete.

      Urgent = 5 seconds, Medium = 7 seconds, and Relaxed = 20 seconds.

      Disable WAFL Sync

      Select this to avoid forcing a WAFL consistency point.

      application settings

    2. Click the Scripts arrow and enter the pre and post commands for quiesce, Snapshot copy, and unquiesce operations. You can also enter the pre commands to be executed before exiting in the event of a failure.

    3. Click the Custom Configurations arrow and enter the custom key-value pairs required for all data protection operations using this resource.

      Parameter Setting Description

      ARCHIVE_LOG_ENABLE

      (Y/N)

      Enables the archive log management to delete the archive logs.

      ARCHIVE_LOG_RETENTION

      number_of_days

      Specifies the number of days the archive logs are retained.

      This setting must be equal to or greater than NTAP_SNAPSHOT_ RETENTIONS.

      Specifies the path to the directory that contains the archive logs.

      ARCHIVE_LOG_EXT

      file_extension

      Specifies the archive log file extension length.

      For example, if the archive log is log_backup_0_0_0_0.161518551942 9 and if the file_extension value is 5, then the extension of the log will retain 5 digits, which is 16151.

      ARCHIVE_LOG_RECURSIVE_SE ARCH

      (Y/N)

      Enables the management of archive logs within subdirectories.

      You should use this parameter if the archive logs are located under subdirectories.
