This is exactly what we do.

Basically, you run two backup storage pool commands for each primary pool to
two different copy pools.  Naming conventions become really important here
to help prevent mistakes and to use masks.

We call our pools like this:

        DSK_                    Primary Disk Pool
        TAPE_                   Primary Tape Pool
        CPY_ONSITE_             Onsite Copy
        CPY_OFFSITE_    Offsite Copy

There is a last qualifier used for all of the same of a pool.  Remember, you
can rename storage pools.

In DRM you can specify a mask for the offsite pools if you want to use the
MOVE DRMEDIA command without specifying a storage pool.  We have a lot of
elaborate code to do this process because we use closed box offsite storage
and manage moving the data on returning tapes to new tapes before they come
backup.  We have recently, started using the location field to hold a lot of
information, such as the return date and issue a MOVE DRMEDIA command for
each tape rather than using "*".  This way the location field in the drmedia
and volumes tables contains lots of information that can be reviewed.  Based
on what I can determine the location field in the drmedia table is derived
from the location field in the volumes table.  So, if you update the
location information in the volumes table it shows in the drmedia table.  By
default the location field is derived from the value in DRMSTATUS as well as
the copy storage pool names.

There are many ways to implement DRM and everyone needs to decide what their
requirements are.  Ours is a unique way.

Hi,

I need to start sending tapes offsite but I want to keep 2 sets of tapes
onsite and have another pool for offsite tapes.
I have the available tapes to use for the offsite pool. I have DRM
installed. Our TSM server is running Version 4.2 Level 1.9 , TSM B/A client
is 4.2 on AIX 4.3.3.
I just need some tips on how to get this going.

thanks,
