About

This manual is a quick configuration guide on how to configure your Linux Sesam server for backing up NetApp NFS volumes via NFS. This version supports backup and restore of NFS shares ONLY!

Note that if you want to set up a NDMP backup, you must configure a task with NDMP task type. For details, see NDMP Backup.

Prerequisites

SEP sesam Server with version at least 4.2.1.x. Check Hardware requirements for SEP sesam Server or RDS.
SEP sesam DataMover for NetApp on Linux (more information see here).
The NetApp system must be reachable over its Web API (http://www.netapp.com/us/products/management-software/) and remote management must be possible via HTTP FilerView.
The backup server must have proper rights to mount the volumes to be backed up locally.
Password and Username of the NetApp system.

Note:

In case your Netapp System is not reachable via FilerView browsing the volumes via SEP Sesam will not work, please see the Troubleshooting section in this document (6.1). This modules works only for NFS shares.

Supported Ontap versions

Sesam 4.4.2.x: Ontap 7.x.x - 8.2.x (7-Mode only)
Sesam 4.4.3.x: Ontap 7.x.x - 8.3.x (7-Mode & Clustered Data)

How it works

In order to be able to backup the files from a certain NetApp volume, Sesam server must have access to it. During a backup run the following things happen:

1) SEP Sesam logs on into the NetApp system and creates a snapshot of the volume
2) SEP Sesam mounts the snapshot locally on its file system
3) SEP Sesam backups the data of the volume
4) SEP Sesam dismounts the volume 
5) SEP Sesam removes the snapshot from the NetApp system

A restore can only be done to an either locally mounted volume or a regular client with a linux operating system on it.

Backup

Adding the client

You have to configure a client to add it to the SEP sesam environment.

In the Main selection -> Components -> Topology, select the desired location to which you want to add the NetApp client and then click New client. Enter the name of the client – this has to be the network host name of the computer. The name has to be resolvable either by DNS or hosts file. If there is a name server (DNS) in the network, SEP sesam automatically selects the TCP/IP address. Otherwise you have to enter it manually in the etc/hosts file.
From the Platform drop-down list, select the relevant platform.
From the Operating system drop-down list, select NetApp.
In the Access mode drop-down list, PROXY communication method is set by default as soon as the NetApp OS is selected.

Then switch to the NetApp Access tab to configure the access and select a data mover.

Configuring access

Under the NetApp Access, set the user name and password for your NetApp system. From the Data Mover drop-down list, select your SEP sesam Server:

Adding a backup task

After creating and configuring the client, switch to "Tasks by Clients" and create a new backup task for the system you have added beforehand, during the browse of the NetApp system a list of volumes to be backed up should appear as shown in the screenshot below. Note that if you want to set up NDMP backup, you must configure a task with NDMP task type. For details, see NDMP Backup.

A backup task can only backup one volume at a time, if you want to backup multiple volumes please create a backup task for each volume seperately and group the tasks using a task group.

Adding a CIFS backup task

For a NetApp CIFS share backup see this article.

Restore

Restore to the original Volume

In this case the data is directly restored to the original volume on the NetApp system it was saved from before. In order to do this, simply start your recovery wizard and select the files to restore. The restore target consists of the volume name (default) and a directory to specify.

Note:

In case you restore to the original volume the system which acts as data-mover must have write access to the volume you are restoring to!

For example:

Netapp restore 1.jpg

For example if the data was saved from a volume which name is "test", and the data should be restored to the folder "testrestore" the restore target is specified as follows:

test:/testrestore

like shown in this example:

Netapp restore 2.jpg
