Has anyone worked much with this combo?
I set up Staging from the GUI, and when the file device hit 90%, our main
backup stopped, and started staging the data on the hard drive off to tape.
Unfortunately, this took 7 hours, and the backup window for the main server
was closed.  This had the effect of preventing us from having a backup that
night.
Not a Good Thing.  The GUI staging window is now permanently disabled.  I
don't understand when Legato designed it this way.????

Now, I am currently using the following command line to stage during the day

nsrstage -v -b 'Daily Jukebox' -m -S `mmingo -a -r ssid -q 'volume=Daily
HardDrive'`

This works well. Moves all data from the hard drive to the tape drive during
the day, and leaves the hard drive free to accept data at night.  It has the
added benefit of one save stream on tape at a time, with no multiplexing (on
tape).

I would like to change the above command to allow it to select the backups
from the previous night to tape, but NOT stage data from the night before.
IE, I want to keep 2 days data on the hard drive, backup the latest data to
tape, and then delete the 2 day old data from the hard drive before the next
backup (Whew!!!)
This will take 2 commands.
1. Command to stage only data in the last 24 hours to tape (minus the -m to
migrate above),
2. And one to clean up the 2 day old data before the beginning of the next
backup, without deleteing the 1 day old data staged in 1. above.

Any comments or thoughts anyone?
