Disk Requirements for Offhost Backup

122 NetBackup ServerFree Agent System Administrator’s Guide

Disk Requirements for Offhost Backup

For offhost backups (NetBackup Media Server or Third-Party Copy Device offhost

backup method), the client’s data must be on one or more disks that meet the following

criteria:

◆ The disk must be either a SCSI or Fibre Channel device.

◆ The disk must be visible to both the NetBackup client and to the NetBackup media

server. The disk must be connected through a fibre channel SAN or through a disk

array that has dual port SCSI connections.

◆ The disk must be able to return its SCSI serial number in response to a serial-number

inquiry (serialization), or the disk must support SCSI Inquiry Page Code 83.

ALL_LOCAL_DRIVES

The policy’s file list must not contain the ALL_LOCAL_DRIVES entry if you are using

offhost backup (NetBackup Media Server or Third-Party Copy Device offhost backup

method).

Multiplexing

The Third-Party Copy Device backup method is incompatible with multiplexing (the

writing of two or more concurrent backup jobs to the same storage device). To prevent

multiplexing on a third-party copy backup, you must set Maximum multiplexing per

drive to 1 (on the “Add New Storage Unit” or “Change Storage Unit” dialog).

Raw Partition Offhost Backups

When entering a raw partition in the file list for an offhost backup, do not specify a block

device as the raw partition. NetBackup 4.5 does not support offhost backups of block

devices. Instead, specify the raw partition as a character device.
