Setting up for NetBackup management

Requirements to support NetBackup administration

To set up SnapVault support for NetBackup transfers to storage systems, your configuration must meet the following requirements:

The primary storage systems must be running Data ONTAP software version 6.5.1 or later.
The secondary storage systems must be running Data ONTAP software version 7.1 or later.
Snapvault must be licensed and enabled on the primary and secondary storage systems.
NDMP service must be enabled on the primary and secondary storage systems as well as the NetBackup management station.
The VERITAS NetBackup management station must be running NetBackup software version 6.0 or later.

What you need to do to enable SnapVault with NetBackup

You need to complete the following tasks to activate a SnapVault NetBackup relationship:

If SnapVault is not already licensed on the primary and secondary storage systems, enter the appropriate license on each system.
Set options snapvault.enable on for both the primary and secondary storage systems to enable SnapVault data transfers and Snapshot creation.
Enable the NDMP service, ndmpd on, on both the primary and secondary storage systems.
Set up options snapvault.access to allow the primary and secondary storage systems to exchange data.
- Setting this option on the SnapVault primary storage system determines which secondary storage systems can access data from that primary storage system.
- Setting this option on the SnapVault secondary storage system determines which SnapVault primary storage systems can access the secondary storage system.
Set up options ndmpd.access to allow NetBackup access to both the primary and secondary storage systems.

Configuring the primary and secondary storage systems

On each primary and secondary storage system log in to that system's console and complete the following steps:

Step	Description
1	Set up the SnapVault primary and secondary licenses on each storage system. Enter the following commands: pri_system> license add sv_primary_license sec_system> license add sv_secondary_license
2	Enable the NDMP service on each storage system. Enter the following command: ndmpd on
3	Add a new backup user to the Backup Operators useradmin group list. Enter the following command: `useradmin user add backupuser -g "Backup Operators"`
4	Generate an NDMP password for the new user. Enter the following command: `ndmpd password backupuser` The NDMP password is used to authenticate the NetBackup media server to the storage system. This password is required for setup on the NetBackup management station. Note It is important to avoid using `root` as an NDMP password because `root` is not encrypted, and could compromise the integrity of your storage system.
5	Enable SnapVault on each storage system. Enter the following command: options snapvault.enable on
6	Use the `options snapvault.access` command to allow access between both the primary and secondary storage systems. On each primary system, specify the name of the secondary host. options snapvault.access host=secondary On each secondary system, specify the name of the primary host(s). options snapvault.access host=primary1,primary2,primary3
7	To specify the name of the NetBackup management station on both the primary and secondary storage systems, enter the following command: options ndmpd.access host=netbackup_server1 Note The primary storage system must be able to resolve the host name to an IP address in the /etc/hosts file, or else the system needs to be running DNS or NIS. You can also use the literal IP address instead of the host name. See the na_protocolaccess(8) man page for details. For more information about the `options` command, see the na_options(1) man page.

Disabling SnapVault schedules

Existing SnapVaulted qtrees are designated as NBU SnapVault when NetBackup establishes a relationship with the storage system. This does not modify or interrupt SnapVault Snapshot scheduling, and might continue to increment the total number Snapshot copies per volume. To control the number of data transfer operations, SnapVault Snapshot schedules should be disabled.

To prevent SnapVault from attempting to update NetBackup managed qtrees, use the snapvault snap unsched command to disable incremental backups for all NBU SnapVault volumes.

To display the currently configured Snapshot schedule, enter the snapvault snap sched command and view the basenames of all Snapshot sets for all SnapVault volumes on the storage system.

Example

system> snapvault snap sched

To turn off existing Snapshot schedules for the SnapVault secondary storage system, enter the following command:

snapvault snap unsched <volume_name> <snap_name>

Note
This command does not end the SnapVault relationships between the secondary qtrees and their primary source qtrees.

Checking the status of a transfer

To check the status of a data transfer use the snapvault status command to see how recently a qtree has been updated. Additionally, you can use the snap list command to view SnapVault qtree relationships involved in the most recent transfer from a primary qtree to a secondary qtree. This display can be used to confirm what versions of your primary qtree data have been backed up, or to locate by date or time a particular version of a qtree.

The NetBackup catalog

The NetBackup catalog is an internal database that resides on the NetBackup management station. This database contains a record of all backup activity and information about the media and storage devices. The NetBackup catalog can be used to monitor and view SnapVault qtree archives.
