In addition to:
BACKUP STGPOOL onsitetape offsitetape
I recommend you do:
BACKUP STGPOOL diskpool offsitetape
Because at any point in time, some of your backup data is in the disk pool,
some in the tape pool.
This makes sure that if there is any data left in the disk pool that has not
migrated to tape yet, it gets copied to the offsitepool. (If there is none
left in the diskpool, then the second BACKUP STGPOOL costs you nothing...)
(In fact, you can save a WHOLE LOT of tape mounts if you do these in the
reverse order.
BACKUP STGPOOL diskpool offsitetape FIRST; then your offsite tapes get made
using only ONE tape mount for the output tape, instead of mounting INPUT and
OUTPUT tapes. :>)
Here is something else you can do:
select stgpool_name, sum(physical_mb)/1024 as physical_GB from occupancy
group by stgpool_name order by stgpool_name
This shows how many GB of data are in your disk and tape pool.
The sum of your diskpool and onsitetape pool should = the GB in your offsite
tape pool. It doesn't prove that EVERY file made it to the offsite tapes,
but if this looks OK when I arrive in the morning, I'm happy..

Subject: Backups missed
Hello,
I have TSM on the mainframe. I have just taken it over and I am still
learning. The previous administrator had administrative schedules
migrating the data from disk to an onsite tape pool and then doing a tape
to tape copy from onsite to offsite tapes. I was wondering how it is
possible for data to not be copied to the offsite pool? If the data is
moved to tape and then it is copied offsite, how is this possible? I know
that you get a message at the end of the job if it was successful or not
and how many files were missed. My problem is I don't have access to the
client side of the servers. I am only in charge of making sure that things
are backed up and running smoothly. Is there an easy way to monitor if
everything is being copied from onsite to offsite tape? Are there certain
error messages that I should be searching for on a daily basis? I'd
appreciate any help that I can get. Thanks!!!!!
Joni
