Configuring a Frozen Image Method

78 NetBackup ServerFree Agent System Administrator’s Guide

9. Select a frozen image method from the picklist.

Note You cannot apply more than one method to the same frozen image source.

For guidance on nbu_snap, fsclone, and vxvm, refer to the “Core Frozen Image

Services”chapter. For TimeFinder, ShadowImage, and BusinessCopy, refer to the

“Extended Frozen Image Services (Array Integration Option)” chapter.

10. If you chose nbu_snap as the frozen image method, specify a raw partition for the

snapshot cache by entering the cache partition’s full path name in the Parameter

Va lu e field.

For example: /dev/rdsk/c2t0d3s3

Do not specify wildcards (such as /dev/rdsk/c2*).

Caution The partition’s contents will be overwritten by the nbu_snap snapshot process.

11. If you chose TimeFinder, ShadowImage, or BusinessCopy as the frozen image

method, specify values for the following. (Note that async_resync is also supported

by the vxvm method.)

synch_at_start: (Enter 0 or 1.) At start of backup, determines whether or not the

primary and mirror devices are automatically synchronized (if they were not already

synchronized) before the backup begins. Specify 1 to have unsynchronized devices

synchronized before the backup begins. 0 means that unsynchronized devices will not

be synchronized before the backup starts. In this case (0), if the primary and mirror

devices are not synchronized, the backup will fail.

async_resync: (Enter 0 or 1.) At end of backup, determines whether or not the backup

job will wait for completion of the resync request. A value of 1 means that a

resynchronize request will be issued, but the backup will not wait for the resync

operation to complete. A value of 0 means that the backup job cannot reach

completion status until the resynchronize operation has finished.

Choosing 1 may allow more efficient use of backup resources. For example, if two

backup jobs using Extended Frozen Image Services need the same tape drive, the

second job can start even though the resync-at-end operation issued by the first job

has not completed.

12. To configure another frozen image source for the client, repeat from step 6.

13. When finished configuring frozen image sources, click OK.

14. To configure a frozen image for another client, repeat from step 3.
