To create a BigData policy using NetBackup CLI method

1. Log on as an Administrator.
2. Navigate to:.

   For Windows:<install_path>\NetBackup\bin\admincmd

   For UNIX:/usr/openv/var/global/bin/admincmd

3. Create a new BigData policy using the default settings.

   bppolicynew policyname

4. View the details about the new policy using the -L option.

   bpplinfo policyname -L

5. Modify and update the policy type as BigData.

   bpplinfo PolicyName -modify -v -M MasterServerName -pt BigData

6. Specify the Application_Type as Hadoop.

   For Windows:

   bpplinclude PolicyName -add "Application_Type=hadoop"

   For UNIX:

   bpplinclude PolicyName -add 'Application_Type=hadoop'

   Note:

   The parameter values for Application_Type=hadoop are case-sensitive.

7. Specify the backup host on which you want the backup operations to be performed for Hadoop.

   For Windows:

   bpplinclude PolicyName -add "Backup_Host=IP_address or hostname"

   For UNIX:

   bpplinclude PolicyName -add 'Backup_Host=IP_address or hostname'

   Note:

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

8. Specify the Hadoop directory or folder name that you want to backup.

   For Windows:

   bpplinclude PolicyName -add "/hdfsfoldername"

   For UNIX:

   bpplinclude PolicyName -add '/hdfsfoldername'

   Note:

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

9. Modify and update the policy storage type for BigData policy.

   bpplinfo PolicyName -residence STUName -modify

10. Specify the IP address or the host name of the NameNode for adding the client details.

    For Windows:

    bpplclients PolicyName -M "MasterServerName" -add "HadoopServerNameNode" "Linux" "RedHat"

    For UNIX:

    bpplclients PolicyName -M 'MasterServerName' -add 'HadoopServerNameNode' 'Linux' 'RedHat'

11. Assign a schedule for the created BigData policy as per your requirements.

    bpplsched PolicyName -add Schedule_Name -cal 0 -rl 0 -st sched_type -window 0 0

    Here, sched_type value can be specified as follows:

    Schedule Type	Description
    FULL	Full backup
    INCR	Differential Incremental backup
    CINC	Cumulative Incremental backup

    The default value for sched_type is FULL.

    Once you set the schedule, Hadoop data is backed up automatically as per the set schedule without any further user intervention.

12. Alternatively, you can also perform a manual backup for Hadoop data.

    For performing a manual backup operation, execute all the steps from Step 1 to Step 11.

13. For a manual backup operation, navigate to /usr/openv/var/global/bin

    Initiate a manual backup operation for an existing BigData policy using the following command:

    bpbackup -i -p PolicyName -s Schedule_Name -S MasterServerName -t 44

    Here, -p refers to policy, -s refers to schedule, -S refers to master server, and -t 44 refers to BigData policy type.
