Hi:
We will be implementing DRM in the next several months, but I have used the 
following method for the last year:
during the day the changes to the storage pools are copied to the copypool 
"OFFSITEVOLS"
as the volumes are allocated they have a status of read/write (or not offsite)
in the afternoon when all data is copied to the copypool, a cron job backs up 
the database and configuration files, then executes a select ( code fragment 
below) to get a list of volumes in the "OFFSITEVOLS" copypool. This is then fed 
into a routine to check out the volumes and change their status to 'offsite'
I then use ACCESS to generate reports of the current % utilized and % 
reclaimable on the offsite volumes and at the end of each month retrieve those 
volumes that are at a set % utilized. These are reentered into the library, the 
access is set readw, the volumes are checked in, and I do move data to move the 
remaining data to other volumes in the copypool and return those to the scratch 
pool.

( I hope DRM does not prove to be a more cumbersome process.)

Hello Everyone,
 
            I am currently looking into ways to do offsite storage.  We have
determined that the DRM software is not needed here.  We run a small system
and this software is better off on a large system.   I was wondering if
anyone could give me an idea on how they are doing it.  One of our options
is to run an archive nightly and ship that offsite.   Does anyone have a
different idea.
 
 
Any help would be appreciated.
 
Thanks,
