Adding a tape library

You can use the configuration wizard to add and configure a physical tape library. The wizard lets you configure the device for shared access if it is connected to multiple hosts.

In the Navigation pane, click Guided Configuration, and then on the NetVault Configuration Wizard page, click Add Storage Devices.
In the Navigation pane, click Manage Devices, and then click Add Device.
On the Add Storage Devices page, select the Tape library/media changer option, and click Next.
Click Next to scan the selected client and list the attached devices.
In the Choose library table, select the device that you want to add.
In the Device display name box, specify a display name for the tape library.
Click Next.
If the library is not configured automatically, click Add drives manually. You can also use this method to assign the drives to different clients or to share the drive with multiple clients.
In the Choose Machine table, select the client to which the drive is attached. If the device is connected to multiple clients, select any one client.
Scan for devices: To scan the client again for attached devices, select this option.
Do not scan for devices: To use the previous scan results, select this option.
Scan only filer: To scan for devices attached to a particular filer, select this option, and then select the applicable filer.
This option is only displayed if you have installed the Plug-in for NDMP on the server and added a filer to the plug-in.
Click Next.

To leave the remaining bays empty and complete the library addition with the required drives, click Leave remaining bays empty.

In the Choose drive for bay table, select the device that you want to add, and click Next.
If the device is connected to multiple clients (for example, in a SAN setup), all host clients are listed in the Choose Machines table. To share the drive with multiple clients, select the clients in the Choose Machines table, and click Next.
To assign additional drives for the library, click Add more devices, and repeat Step a through Step c until all required drives are configured.


Backing up data

About backing up data

A backup is a copy of data, which can be used to restore and recover the original data after a data loss event.

NetVault Backup offers a selection of plug-ins, which integrate with the native APIs to provide application-consistent backups and recovery of data. Depending on the application type, these plug-ins provide multiple methods and options to back up the selected data.

In general, NetVault Backup supports the following features:

To back up your data, you must create and submit a backup job. The NetVault Backup WebUI provides a configuration wizard that helps you to perform this task. You can run the wizard from the Guided Configuration or Create Backup Job link in the Navigation pane.

A backup job definition includes the following components:

Source device options (available only to the Plug-in for Consolidation, Plug-in for Data Copy, and Secondary Copy jobs)

These components are stored in NetVault Backup Sets. For more information about NetVault Backup Sets, see About NetVault Backup Sets.

Each backup job has a Job ID number and a Job Name. The Job ID number is an auto-generated number. The Job Name is a user‑defined string, which allows you to easily identify the job when monitoring its progress, viewing the job logs, or selecting a backup to restore data. A backup is stored as a Saveset on the media.

NetVault Backup generates a backup index for each backup, and writes this index to the backup media and NetVault Database.

The backup index includes a header which contains information required for restoring data. There is no maximum limit on the index file size or the number of items that you can include in a backup job.

Backup indexes stored in the NetVault Database are called Online Indexes. Online indexes allow you to quickly scan through the contents of a saveset without loading the media.

Secondary Copy

With a backup job, you can choose to run a Phase 2 job to create a Secondary Copy, which can be used for off‑site storage and disaster recovery purposes. NetVault Backup provides two methods to create a Secondary Copy: Duplicate and Data Copy.

The Duplicate method creates an exact copy which is linked to the original backup. This method breaks down the backup into segments and copies the segments to the storage device. During restore, the segments from the primary backup and secondary copy are interchangeable. As it is not possible to mix unencrypted segments with encrypted segments during restore, you cannot enable or disable encryption for the Duplicate. If the original saveset is encrypted, the Duplicate method creates an encrypted copy. If the original saveset is not encrypted, this method creates an unencrypted copy.

The Data Copy method breaks down the backup into segments and copies the segments to the backup device. During restore, either the primary backup or the secondary copy is used to recover data; the segments from the primary backup and secondary copy are not interchangeable. Therefore, it is possible to enable encryption for the Data Copy when the primary copy is unencrypted. This option is useful when you want to use the deduplication option for primary backups.
