Using the NetBackup Policies utility to create a BigData policy for Hadoop clusters

Use the following procedure to create a BigData policy with the NetBackup Policies utility.

To create a BigData policy with the NetBackup Policies utility

  1. In the NetBackup Administration Console, in the left pane, expand NetBackup Management > Policies.
  2. On the Actions menu, click New > Policy.
  3. Type a unique name for the new policy in the Add a New Policy dialog box.

    Click OK.

  4. On the Attributes tab, select BigData as the policy type.
  5. On the Attributes tab, select the storage unit for BigData policy type.
  6. On the Schedules tab, click New to create a new schedule.

    You can create a schedule for a Full Backup, Differential Incremental Backup, or Cumulative Incremental Backup for your BigData policy. Once you set the schedule, Hadoop data is backed up automatically as per the set schedule without any further user intervention.

  7. On the Clients tab, enter the IP address or the host name of the NameNode.
  8. On the Backup Selections tab, enter the following parameters and their values as shown:
    • Application_Type=hadoop

      The parameter values are case-sensitive.

    • Backup_Host=IP_address or hostname

      The backup host must be a Linux computer. The backup host can be a NetBackup client or a media server.

      You can specify multiple backup hosts.

    • File path or the directory to back up

      You can specify multiple file paths.

      Note:

      The directory or folder specified for backup selection while defining BigData Policy with Application_Type=hadoop must not contain space or comma in their names.

  9. Click OK to save the changes.
