To create a BigData policy for Hadoop clusters

2. On the left, click Protection > Policies.
3. On the Policies tab, click Add.
4. On the Attributes tab, for the Policy type select BigData.
5. On the Schedules tab, click Add 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. After you set the schedule, Hadoop data is backed up automatically as per the set schedule without any further user intervention.

7. 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 that is specified for the backup selection when you define a BigData Policy with Application_Type=hadoop must not contain a space or a comma in their names.

8. Click Create.
