Optimizing Legato Networker Disk Space Usage

[Michael42]

Hello,

I could use some suggestions of how to optimize Legato Networker on UNIX (Sun) so as to take up less disk space.

For instance, I noticed if I delete a client using the GUI the indexes and other references still remain. I have a lot of ancient clients that I would like to purge all references to.

Thanks,

Michael42

Once you deleted the client, NW is not aware of it any more.
You may now delete the /nsr/index/client_name directory.

Thanks, this is very useful!

FYI, If you delete the client without deleting the savesets from the media database the save sets will never expire.

Goal
-------
How to delete database entries for deleted clients

Goal
-------
Why does NetWorker show media entries for clients that no longer exist?

Fact
-------
NetWorker

Fact
-------
Client has been deleted from Networker

Cause
-------
Clients were deleted from NetWorker before all of their save sets had expired. Consequently, NetWorker did not enforce browse or retention policies on those save sets, and then will never become eligible for recycling.
