Greetings ADSMers,
    I have a customer with an unusual request, but what they want is a
perfectly legitimateconcern.  They have some very critical data that
need to archive on a daily basis, and then they want to delete the data
as soon as a good copy gets to tape.  There is too much data being
generated this way to keep it around for more than a few days.
    The problem is, they don't exactly trust tape, and with good
reason.  They use DLT7000s, and they get a bad tape about once a month
or so.  The backups and archives go straight to tape, and seem to be
fine, but then when they try to make a copy storage pool to send the
data offsite, they find a bad tape, and some of the data can't be read.
With backups this is not too critical, since usually the original is
still there, and the next backup picks it up once the bad tape is
deleted.
    But with the archives, the goal is to be able to delete the original

copy as soon as the archive gets done.  The only way I can think of to
satisfactorily handle this is to archive the file, then wait a couple
days, and then from a script figure out if a certain file has been
archived, and also that the copy storage pool copy has also been
successfully made.  This proves at least that the first copy was a good
one, otherwise the backup storage pool would have failed.  Once the
script determines that there are two copies of the archive, then it is
considered safe to delete the original.
    Does anybody already have a script that does something like this?
Is is hard to find out if a certain file has made it to the copy storage

pool?

Thanks for any suggestions.
John Schneider
