Create resource groups and attach policies in Snapcenter

Contributors netapp-nsriram netapp-soumikd netapp-ivanad

A resource group is the container to which you must add resources that you want to back up and protect. It enables you to back up all the data that is associated with a given application simultaneously. 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.

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

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

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

    For this field…​ Do this…​


    Enter a name for the resource group.

    Note: The resource group name should not exceed 250 characters.


    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 the 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. Optional: In the Resources page, select a host name from the Host drop-down list and the 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 select the right arrow to move them to the Selected Resources section.

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

    1. Select 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.

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