About storage devices

NetVault Backup supports a wide range of devices for storing backups. The supported devices include disk-based storage devices, deduplication appliances, physical tape libraries, autoloaders, tape drives, Virtual Tape Libraries (VTLs), and Shared Virtual Tape Libraries (SVTLs).

You can attach the storage devices to the NetVault Backup Server, Clients, or NAS filers in a NetVault Backup Domain. The physical storage devices can be configured for single or shared use, and connected through SCSI, iSCSI, IP, SAS, or Fiber Channel SAN interfaces.

To use a storage device in a backup or restore operation, you must first add the device to the NetVault Backup Domain. A device attached to a NetVault Backup Client is only recognized after you add the client to the NetVault Backup Server. Similarly, a device attached to a filer is only recognized after you add the filer to the server using NetVault Backup Plug-in for NDMP (Plug-in for NDMP). The MSP administrators create tenant specific media groups on the storage devices. These media groups are then assigned to the respective tenant user groups, or multiple tenant user groups of the same organization. For more information on:

•
Assigning tenant specific media groups, see Configuring client and media group memberships
•
Adding tenant user groups, see Managing AD groups

Tenants can access only those media groups which are assigned to them.

 
* 
NOTE: Tenant administrator and tenant user is not permitted to add/attach any new storage device to the NetVault Backup Server. However, tenant administrator can add Snapshot Array Manager, once added it is accessible to tenant users for snapshot enabled backups.

SAN considerations

The following requirements apply to a SAN environment:

•
In a SAN environment, you must use persistent binding (also known as SCSI mapping, persistent reservation, or persistent naming).
NetVault Backup cannot communicate with a library if its logical address changes as a result of changes in the SAN. Persistent binding assigns a fixed logical address to the device. This address does not change as devices are added or removed in the SAN.
For Fiber Channel Host Bus Adapters (HBAs), you can map the Fiber Channel device address (World Wide Name (WWN) or World Wide Identifier (WWID)) or Loop ID to the logical SCSI address. This configuration ensures that the changes in the SAN have no impact on the NetVault Backup operations.
•
You must also use persistent binding when the server and fiber devices are attached to separate switches or when zoning is implemented.
NetVault Backup does not support multipathing to a tape library or device. To ensure consistent communication path, you must configure only one logical or physical channel for use.
You should not use tape libraries or drives on the same switch or in the same zone that has disk devices attached. Problems might be encountered if packets from both device types co-exist in a SAN environment. Therefore, you should use separate HBAs for these devices.
•
Apple supports multipathing in FC Host Adapter and XserveRAID. Multipathing is often the default setting after installation. However, multipathing is not supported in NetVault Backup. Therefore, the connections should be logically or physically separated to ensure a consistent communication path.
