Deleting backup images
Image deletion may be time consuming. Therefore, if you delete images manually,
Symantec recommends the following approach.
See
on page 118.
To delete backup images manually
1
Expire 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.
2
After you expire the last image, delete all of the images by using the
nbdelete
command with the
–allvolumes
option.
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
1
In the NetBackup Administration Console, expand NetBackup Management
> Host Properties > Master Servers.
2
In the details pane, select the master server.
3
On the Actions menu, select Properties.
4
On the Host Properties Client Attributes General tab, select the client that
deduplicates its own data.
5
In the Deduplication Location drop-down list, select Always use the media
server.
6
Click OK.
