Simon,

If you want to expire an image on disk, it is the same procedure as on tape.
Images written to disk are copy #1, so find the image name and specify copy #1.
You can query the db to find the actual path and copy number.  For testing
I can see this being useful, just remember for production you will want
phase 2 to complete successfully before expiring images.

I never found a way to convert a dsu to a dssu, so I've always destroyed it
and started again.  Once that is done, you can either set up the schedule
or kick it off manually "bpbackup -dssu DSSU_NAME"

Length and durations and phase 2 frequencies are definitely not a one size
fits all situation.  Really generally comes down to business requirements
plus capital expenses and then work backward from there...  Maybe you have
some restore SLAs that can help make some decisions.

Thanks
Peter
