Symantec 7 manual Deleting backup images, Disabling deduplication for a client

90Managing deduplication Deleting backup images

Deleting backup images

Image deletion may be time consuming. Therefore, if you delete images manually, Symantec recommends the following approach.

See “Data removal process” on page 118.

To delete backup images manually

1Expire all of the images by using the bpexpdate command and the

-notimmediate option. The -notimmediate option prevents bpexpdate from calling the nbdelete command, which deletes the image.

Without this option, bpexpdate calls nbdelete to delete images. Each call to nbdelete creates a job in the Activity Monitor, allocates resources, and launches processes on the media server.

2After you expire the last image, delete all of the images by using the nbdelete command with the –allvolumesoption.

Only one job is created in the Activity Monitor, fewer resources are allocated, and fewer processes are started on the media servers. The entire process of expiring images and deleting images takes less time.

Disabling deduplication for a client

If you remove a client from the list of clients that deduplicate their own data,

NetBackup backs up the client normally.

To disable client deduplication for a client

1In the NetBackup Administration Console, expand NetBackupManagement > Host Properties > Master Servers.

2In the details pane, select the master server.

3On the Actions menu, select Properties.

4On the Host Properties Client Attributes General tab, select the client that deduplicates its own data.

5In the Deduplication Location drop-down list, select Always use the media server.

6Click OK.
