Notes on Offhost Backup and Frozen Images

56 NetBackup ServerFree Agent System Administrator’s Guide

Note Be sure to specify the actual character special device file. nbu_snap will not work for

block special device files.

The basic requirements for the cache partition are:

◆ Must reside on the same host as the frozen image source that you have

specified.

◆ Must be unmounted.

◆ Must have enough space to hold all the writes to the partition that may occur

during the backup. Note that backups during nonworking hours normally

require a smaller cache than a backup during peak activity.

Backup Policy Configuration Wizard

The Backup Policy Configuration Wizard helps you set up a basic NetBackup class

(policy). If you used this wizard to configure a class for NetBackup 4.0V, please note the

following:

◆ If you chose Back up all local drives, the wizard placed an entry called

ALL_LOCAL_DRIVES in the class file list. NetBackup 4.0V does not support the

ALL_LOCAL_DRIVES option for offhost backup (either NetBackup Media Server or

Third-Party Copy Device). For offhost backups, be sure to remove the

ALL_LOCAL_DRIVES entry from the class file list (use the Files tab on the Change

Class dialog).

◆ The wizard automatically sets your storage device to Any_available. This is okay for

local backups. To use an offhost backup method (Third-Party Copy Device or

NetBackup Media Server), you must select a particular storage unit—do not select

Any_available.

FlashBackup Classes

When applying a ServerFree Agent frozen image method to a client in a FlashBackup

class, note the following:

◆ The nbu_snap and vxvm frozen image methods are valid for clients in a FlashBackup

class. The fsclone frozen image method, however, is not valid for clients in a

FlashBackup class. Although the Frozen Image Client Configuration dialog allows

you to select fsclone for such clients, the backup will fail.

◆ For a FlashBackup class containing a client configured with a frozen image method as

described earlier in this chapter, the file list should specify the files(s) but not the

cache partition (do not include the CACHE= entry). The cache partition is specified in

the Frozen Image Client Configuration dialog, explained under “Configuring a

Frozen Image Method”in this chapter.
