Chapter 5, NetBackup Configuration 85

Configuration Tips

FlashBackup Policies

When applying a frozen image method to a client in a FlashBackup policy, note the

following:

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

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

FlashBackup policy. Although the Frozen Image Client Configuration dialog allows

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

◆ For a FlashBackup policy 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). For the nbu_snap method, the

cache partition is specified in the Frozen Image Client Configuration dialog,

explained under “Configuring a Frozen Image Method” on page 76.

However, for a FlashBackup policy that does not contain any clients configured with a

frozen image method, the file list must specify the files(s) AND a cache partition (the

CACHE= entry). Refer to the NetBackup FlashBackup System Administrator’s Guide.

Multiple Data Streams

Note Multiple data streams are not supported for the Third-Party Copy Device method.

In NetBackup, if the Allow multiple data streams policy attribute is selected, all streams

must be set to Active for the backup to be successful. This means that all streams must be

able to start at the same time (no backups can be queued waiting for others to complete).

For backups, make sure that the following are set to allow the number of active streams to

be equal to or greater than the number of streams in the file list:

◆ Policy attribute: Limit jobs per policy

◆ Schedule setting: Media multiplexing

◆ Storage unit setting: Maximum multiplexing per drive

◆ System configuration setting: Maximum jobs per client
