Setting up SnapVault support for NetBackup transfers

Requirements

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

The storage system must be a NearStore.
The NearStore system must be running Data ONTAP software version 7.1 or later.
A SnapVault secondary license must be enabled on the NearStore system.
NetBackup Enterprise 6.0 on the master server and media server
NetBackup client systems must be running NetBackup 5.0 or later.
NDMP service must be enabled on the NearStore system.
An NBU volume must be a FlexVol volume.
Note
NBU volumes support only NetBackup data transfer and storage operations. Therefore, it is important to disable SnapVault schedules and release SnapVault relationships on NBU volumes. See, Disabling SnapVault schedules, and Releasing SnapVault relationships for more information.

Configuring NearStore as a secondary storage system

To configure the NearStore as a secondary storage system. Complete the following steps

Step

Description

1
Set up the SnapVault secondary license. Enter the following command:

license add sv_secondary_license

2
Add a new backup user to the Backup Operators useradmin group list. Enter the following command:

useradmin user add backupuser -g "Backup Operators"

3
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 NearStore storage system. This password is required for NearStore 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.

4
Enable SnapVault. Enter the following command:

options snapvault.enable on

5
Use the options snapvault.access command to specify the names of the NetBackup media servers. Enter the following command:

options snapvault.access host=netbackup_server1, netbackup_server2 ...

Note
NetBackup client connect requests are received on TCP port 10571.

.

Step	Description
1	Set up the SnapVault secondary license. Enter the following command: license add sv_secondary_license
2	Add a new backup user to the Backup Operators useradmin group list. Enter the following command: `useradmin user add backupuser -g "Backup Operators"`
3	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 NearStore storage system. This password is required for NearStore 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.
4	Enable SnapVault. Enter the following command: options snapvault.enable on
5	Use the `options snapvault.access` command to specify the names of the NetBackup media servers. Enter the following command: options snapvault.access host=netbackup_server1, netbackup_server2 ... Note NetBackup client connect requests are received on TCP port 10571.

NBU NearStore and NBU SnapVault cannot share a volume

NBU NearStore software and NBU SnapVault functionality cannot share the same volume. To prepare a FlexVol volume to support NetBackup:

Disable any incremental backups to the secondary qtrees that were originally scheduled for the FlexVol volume
Release existing SnapVault relationships

Disabling SnapVault schedules

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 system qtrees and their platform source drives or directories.

To disable Snapshot schedules on the volume:

snap sched <volume_name> 0 0 0

Releasing SnapVault relationships

To release SnapVault relationships and free the space on the volume, enter the following commands.

Step	Action
1	Enter one of the following commands. On the primary system console, enter: snapvault release prim_qtree_path sec_system:sec_qtree_path On the secondary system console, enter: snapvault release sec_qtree_path prim_system:prim_qtree_path

Example

system> snapvault release /vol/sv_vol/qtree3 
systemA:/vol/vol1/qtree3
