NetVault Plug-in for SnapVault Manager 10.0.1 - User Guide

Establishing relationship on SV Primary

With a service set up and in place on an SV Secondary, the next step is to establish Relationships between each SV Primary and the Service.

1
On the NetVault Backup Selections page, open the SV Primaries node.
2
In the list of added SV Primaries, open the applicable SV Primary to display the available volumes and drives.
3
Browse through the selections tree and locate the directory or qtree that you want to back up.
4
Select the item, and in the Actions list, click Add Relationship.
5
In the Add Primary Relationship dialog box, configure the following options.
Option
Description

Name

Type a name for the Service. Valid characters include, A–Z, 0–9, “-” (hyphen), and “_” (underscore). This parameter is required. After the Service is successfully configured, this name is how it is displayed in NetVault Backup when creating a Relationship between it and an SV Primary.

Enable All Relationships

This check box is selected by default. It indicates that the Relationship is enabled after it is created. To disable the relationship, clear this check box from the Edit Relationship window. You can also disable it on a per Service basis using the Enabled option in the List of Configured Services.

Default Throttle

Type a value that serves as a “throttle” for data transfer. The value must be specified in Mb/s. The larger the value input, the larger the amount of bandwidth used. The default of “0” indicates that no set value is to be used and NetVault Backup attempts to use the maximum allowable amount.

List of Configured Services

As a Service is configured on the SV Secondary, it is made available in this list. For each Service, the following options are available:

•
Use: To use this Service, select this option.
•
Secondary: The name of the SV Secondary containing the Service.
•
Volume: The path and name of the volume in use on the SV Secondary for this Service.
•
Service: The name given to the Service.
•
Throttle: This option lets you override the Default Throttle settings, and set individual “throttle” values for the configured services.
•
Offset: This option lets you override the Default Primary Update Offset settings, and set individual Update Offset values for the configured services.
6
To establish the Relationship, click OK.
Items with Relationships set for them are marked by a large black “R” in the selection tree.

Initial synchronization and updates

With the steps successfully performed in both adding a Service and establishing a Relationship, the Initial Synchronization (the initial Full Backup) automatically occur (you do not have to submit a backup job to begin the backup process). Updates (Incremental Backups) are periodically performed based on how they were scheduled in the selected Service on the SV Secondary.

* 
IMPORTANT: If a time frame was established for the Initial Synchronization, either through the Default Initialization or Initialization windows, it occurs in that time frame. Otherwise, it begins when the Relationship is generated as a result of the default settings for the Plug‑in for SnapVault Manager.
Viewing initial synchronization and update progress

Although you do not have to submit a backup job, you can still view the progress of a SnapVault job on the Job Status page. To access this page, click Job Status in the Navigation pane.

Available commands in the Actions list

The following sections provide a brief description of the items that are displayed in the Actions list when you select a configured Service and Relationship.

Available commands for volumes within an SV Secondary

The Actions list includes the following items a volume within an SV Secondary:

•
Open: Open the selected item and displays its contents. This command is replaced by the Close command after an item has been opened.
•
Add Service: Allow you to add a service for the selected volume. For more information, see Establishing service on SV Secondary.
•
Unused Relationships: Allows you to remove Relationships that do not use any Service.
When you select this command, the Unused Secondary Relationships dialog box is displayed. This dialog box lists the eligible Relationships. For each Relationship, it includes information about the Path, Primary System Name, and Relationship Name.
To remove a relationship, select the corresponding Remove check box. To delete any data contained within the associated SV Secondary, ensure that the Delete Data on Secondary check box is selected. If you clear this check box, the data is preserved, but the Relationship is removed. To remove the selected Relationship, click OK.

•
Edit Service: Allows you to edit the current settings for a service.
•
Remove Service: Allows you to remove a service.

IMPORTANT: When more than one service with the same name is created by separate instances of the plug-in, removing the service from SnapVault Manager causes the service to be deleted from the Secondary Filer. This change causes the other instances of the Plug‑in for SnapVault Manager to consider this service as disabled. A disabled service can either be removed or repaired.
Available commands for relationships

The Actions list includes the following items a relationship:

•
Enabled: Allows scheduled updates of a relationship. If this option is not selected, NetVault Backup does not perform any scheduled updates for the relationship. This option is useful if you want to temporarily disable the relationship.
•
Update Relationship: Allows you to initiate an Update (Incremental Backup) immediately. You can use this command to perform manual Updates of the selected SV Primary Relationship data outside of what is scheduled to occur in the Service.

ASIS deduplication of secondary snapshots

Starting with Data ONTAP 7.2.4, NetApp offers a feature called ASIS, which is a feature for deduplicating data in Secondary Snapshots. This feature can offer significant storage savings depending on the type of data being backed up. To perform ASIS deduplication of secondary snapshots, you must configure both the Secondary Filer and the Plug‑in for SnapVault Manager. The configuration steps are outlined in the following sections:

•
Configuring the secondary filer
•
Configuring the plug-in
