Running out of drive space DB is huge.

Ever week I have to clean up the logs. which give me about 11 GB to keep everything moving.

This is a windows server master/media, and also has OPcenter running on it.

Server 2008 R2 standard SP1

64Bit

Drive space is 278GB and I am down to 9.43GB.  Yesterday I had it at 11GB.  

Netbackup 7.5.0.6

Will be upgrading once all out 2000 servers are turned off.

I look at the DB Folder in Netbackup "C:\Program Files\Veritas\NetBackup\db"

and it is 207GB in size..

Is there a way to clean this up?  Or better yet move it to a different drive?

What about moving the log files to a differet drive.

Any help, suggestions etc would be great.  Thank you.
