Change length of time reports are stored for

Hi there,

I'm trying to configure the Reports facility in the NetBackup Adminitsration Console - it currently stores reports for about two weeks but i've been told to extend this to 6 months. I presume this is a configurable option within the Admin Console but i just can't figure out a way to do it. Can anyone help me out? It doesn't seem like a particularly tricky thing to do but i'm stumped.

Thanks for the help!
