    You have created a Basic Disk Storage Unit where Exchange Backups are written to, right?

    Hopefully you have created the DSU on a separate volume and not just a folder on the same volume as the NetBackup installation?

    There are 2 factors that control the lifespan of images on disk:

    1. The retention level specified in Policy schedule
    2. The High Water Mark of the DSU IF you have configured staging to tape.

    HWM is only useful if the DSU is on its own volume and if staging is configured. When the HWM is reached, NBU will cleanup oldest images that have been duplicated to tape until the LWM is reached.
