  1. Send job run reports to: When selected, a job report is sent to specified recipients each time the failback job has completed. This overrides the default setting in the NAKIVO Backup & Replication Settings dashboard.

  2. Run local pre job script: When selected, a dialog box open in which you can specify the following options of the pre-job script to be run:

    • Script path: A local path to the script on the machine where the Director is installed. A script interpreter should be specified as well.

    • Job behavior: The following options are available:

      • Wait for the script to finish: This is the default option.

      • Do not wait for the script to finish.

    • Error handling: The following options are available:

      • Fail the job on script failure.

  3. Run local post job script: When selected, a dialog box opens in which you can specify options of the post-job script to be executed on the machine where the product is installed. Proceed with setting the options as described for Run local pre job script.


Data Transfer

In the Data Transfer section of the Options page, you can select a transport mode and select a Transporter to be used for reading data. Proceed as described in the sections below.

Transport Mode

Transport mode defines the method of VM data retrieval by a source Transporter. Do one of the following:

  • Select Automatic selection to allow the product to choose the best transport mode available. If the product cannot use SAN or Hot Add, LAN mode will be used.

  • Manually select one of the available transport mode options:

Transporter Pool

If this option is enabled, only the transporters that belong to the selected transporter pool shall be used during the job run.

Transporters

By default, the product automatically determines which Transporter should be used to read data from the source VM. However, you can manually specify which Transporters should be used for the job. Here’s how:

In the Data Transfer section, choose one of the following options:

  • Automatic selection: The product will automatically determine which Transporters are the closest to source hosts (the hosts that run selected VMs) and will use those Transporters to retrieve data from source VMs.

  • Manual - configured for all VMs: Select this option to manually specify a single Transporter that will be used to retrieve data from source VMs.

  • Manual - configured per host: Select this option to manually specify which Transporter should be used to retrieve data from each source host.  When selected, the Replacement Transporter drop-down list becomes available. In case a primary Transporter is unavailable, a replacement Transporter will be used. Note that the product selects what Transporter to use (primary or replacement) at the beginning of the job run, not while the job is running.

Transporter Load

You can limit the maximum number of Transporter tasks used by the job. By default, this number is set to 3 concurrent tasks.

To change the default number of tasks, do the following:

  1. In the Data Transfer section, select the Limit transporter load to checkbox.

  2. Specify the number of concurrent tasks in the corresponding box.

Bandwidth Throttling

Follow the steps below to regulate the speed of data transfer over the network for your backup job:

  1. For the Bandwidth throttling option, choose Enabled.

    Note

    If bandwidth throttling is disabled for the current job, global bandwidth rules may still apply to your job. Refer to Bandwidth Throttling for details.

  2. Click the settings link that becomes available.

  3. The Job Bandwidth Rules dialog box opens, displaying the list of available rules. You have the following options:

    • Create a new bandwidth rule for your backup job:

      1. Click the Create New Rule button.

      2. The New Bandwidth Rule dialog box opens. Refer to the Bandwidth Throttling topic for details on creating a bandwidth rule.

      3. Click Save.

    • Activate an existing bandwidth rule for your job. Select the checkbox to the left of the required bandwidth rule. To deactivate a bandwidth rule for your job, deselect the corresponding checkbox.

    • Edit a bandwidth rule. Click the Edit link for a bandwidth rule and modify it in the Edit Bandwidth Rule dialog box that opens.

    • Disable a bandwidth rule. Click the Disable link. The bandwidth rule is disabled for all jobs.

    • Remove a bandwidth rule. Click the Remove link and then click Delete to confirm your operation.

Bottleneck detection

When the Bottleneck detection option is enabled, additional information is collected and recorded in NAKIVO Backup & Replication logs in the course of data transfer for the purpose of bottleneck detection. Check this option to enable the Bottleneck detection capability of the Transporters engaged in the job.

Click Finish or Finish & Run to complete the job creation.


Note
If you click Finish & Run, you will have to define the scope of your job. Refer to Running Jobs on Demand for details.
