Offhost Backup Overview

Offhost Backup Without a SAN

Offhost backup does not require a fibre channel SAN. You can configure a multi-ported

SCSI disk array on a LAN or WAN (as shown below) to support a NetBackup media

server offhost backup. The NetBackup media server performs the data movement.

1. Client backup is initiated by master server, which tells the NetBackup client to map the

frozen image data on the disk.

2. Client sends the mapping information to the media server.

3. Media server processes the backup and reads client data from the addresses specified

by the client.

4. Media server writes data to storage.
