Prerequisites

Before you add Snapshot Array Manager, verify and consider the following requirements:

Adding Snapshot Array Manager

The array manager provides a centralized management console to monitor and manage storage centers. To use the storage arrays for snapshot-based backups and restores, you must add the supported device manager to the NetVault Backup Server running on Windows operating system.

You can use the configuration wizard to add and configure the Enterprise Manager.

1
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.
2
On the Add Storage Devices page, select the Snapshot Array Manager option, and click Next.
3
On the Add Snapshot Array Manager page, provide the following details.

Device display name

Specify a display name for the Enterprise Manager.

Array Manager Type

Select the supported storage array manager from the drop down list.

Network name/IP address

Type the Fully Qualified Domain Name (FQDN) or IP address of the Enterprise Manager.

If the server is unable to resolve the host name, it fails to add the Enterprise Manager.

Network port

Set the port number of supported devices to receive communication from all clients. Following are the default port numbers of supported device managers:

If you have changed the Web Server port on the Enterprise Manager, specify the port number.

Username

Specify a user account that can be used to log on to the Enterprise Manager.

Password

Type the password for the user account.

4
Click Next to add the device.

Virtual Tape Libraries

This section includes the following topics:

About Virtual Tape Library

Virtual Tape Libraries (VTLs) emulate tape libraries on disk. VTLs are included in NetVault Backup as a licensable option.

With VTLs, you have the flexibility to perform quick backups to disks, and during off-peak hours migrate or duplicate the backups to physical devices for off-site storage. The Media Manager does not distinguish between virtual and physical tapes. Therefore, you can use the same process to set up backup policies, including retirement period and rotation schemes.

VTLs are represented as directories on the disk. Each VTL contains three directories: drives, slots, and media. These directories contain numbered subdirectories. The virtual drives reside as files in the drives subdirectories. These files contain links to the media files. The virtual tapes reside as media files in the media directory. When a virtual tape is moved between slot and drive, the media file itself stays in the media directory, while the drives and slots files are modified to emulate the moving of the media.

A VTL can handle any number of concurrent NetVault Backup Client backups. As with a physical library, the number of drives contained in the VTL dictate how many simultaneous operations can be performed. The number of slots should be the same as or more than the number of configured drives. Different operating systems may impose maximum file-size limits, which can affect the maximum VTL media size.
