Creating an NDMP Backup Job

DPX provides generic NDMP support that can back up and restore data for NDMP NAS appliances in several ways.

• High-Speed Local Backup

  The NAS appliance is directly connected to a SCSI-attached or fiber-attached storage device (typically a tape drive). The NAS appliance must be defined in DPX as a node that uses the NDMP access method. DPX documentation refers to these nodes as NDMP nodes. Data is backed up and restored directly via the local device.

• Three-Way Backup

  The NAS appliance sends data over the LAN to a storage device attached to a second NDMP appliance. Both NDMP devices (source and destination) must be defined in DPX as nodes that use the NDMP access method.

• Appliance-to-Server Backup

  The NAS appliance sends or receives data over the LAN to a DPX device server. The NAS appliance must be defined in DPX as a node that uses the NDMP access method. The DPX device server is defined in DPX as system type TCP/IP, though DPX device servers can exchange data with supported NDMP devices.

Web interface

1. Select Job Manager in the sidebar. Then click the New Backup Job button in the upper right corner.

2. Select NDMP as Job Type.
   You may also select the Job Folder to store the job in (for more information, see Job Manager). By default, all jobs are stored in the SS_DEFAULT job folder.
3. Specify the Job Name. For NDMP Backup, this field may contain no more than 64 characters.
   You can also add an optional description (up to 48 characters).

4. Click Add source in the SOURCES pane to specify which buckets you want to back up. The Source selection dialog will appear.

Restrictions.

If you select multiple subdirectories as source objects, DPX will back up their entire common ancestor.

Tip.

You may view your current selection at any moment by clicking the Selected Items button next to the search field.

You can clear each item by clicking theicon next to the item, or clear all items at once using the Clear all button.

To close the Selected Items pane, use the “X” symbol or click anywhere outside the pane.

5. In the BASE BACKUP DESTINATION pane, click Set Destination to choose the destination for the base backup.

Note.

NDMP backup support all types of device clusters and mediapools, including S3.

6. The INCREMENTAL BACKUP DESTINATION and DIFFERENTIAL BACKUP DESTINATION panes are pre-populated as per the base backup destination. You may change that by clicking Set Destination in respective panes. Note that both these destinations are required for saving the job.

Desktop interface

1. In the main desktop interface window, go to the Backup tab, and from the Backup Modes section in the task panel, choose NDMP.

   

   Two additional panes will appear.
   You are already in the defining new file backup job view, so there is no need to click the Define New Backup Job button under Job Tasks in the task panel.

   

2. Specify the NDMP backup source in the middle pane. Expand the tree as necessary.

   Empty checkboxes indicate a directory that will not be included. Checkboxes marked in red indicate a directory that will be fully included. Half-red checkboxes indicate that only some subdirectories/files of a given directory will be included.

3. Specify the NDMP backup destination in the right-hand side pane. Expand the tree as necessary.

Note.

Before running a backup job, you need to save it. Once saved, a previously defined job can be modified, run, or deleted. If you try to leave the job creation view without saving the changes, you will be prompted to either save or discard changes before leaving.

If you select Define New Backup Job, all unsaved changes will be lost.

4. Set advanced options as desired, selecting appropriate items in the Other Tasks section of the side panel. Scroll down if necessary.

   • Select File > Save Job
   • Select Save Backup Job in the Job Tasks section of the side panel

   The Save Job dialog will appear.

   

Restrictions.

The new job name must be unique throughout the entire DPX, regardless of the folder the job is stored in.

6. Click OK.
   The job is now saved.
