Configuring Devices for Direct Backup

This section provides the configuration steps for backup devices used in a direct backup environment. Refer to the HP OpenView Storage Data Protector Concepts Guide for a more detailed information on direct backup concepts.

Direct backup is a Data Protector backup solution in a SAN environment. Please read the section “Shared Devices in the SAN Environment” on page 44 for general information on SAN environments. Note that the direct backup device configuration steps differ from the configuration steps described in the mentioned section, and are given in this section.

A direct backup environment consists of the following:

•a SAN network

•internal or external Fibre Channel bridge(s) (FC bridge)

•backup device(s) connected to FC bridge(s) (standalone or SCSI-II library)

•physical XCopy engine(s) (present on an FC Bridge)

•disk array(s) assuring point-in-time stability of data (HP StorageWorks Disk Array XP or HP StorageWorks Virtual Array)

•application system(s) connected to the disk array original disk(s)

•backup system(s) connected to the disk array mirror disk(s) and controlling the SCSI-II library robotics and SCSI-II library/standalone device drives

An internal FC bridge is embedded in the backup device, whereas an external FC bridge resides at any point in the SAN.

A backup device used in the direct backup environment is identified by the World Wide Name (WWN) of the Fibre Channel bridge that it is connected to or embedded in the backup device, and by the device (standalone device) or drive (SCSI-II library) Logical Unit Number (LUN) as seen on the SAN. If a SCSI-II library is used, its robotics does not have to be connected to a FC bridge.
