Kevin:

Thanks for the info...  I have yet to receive the RED books from IBM, but
have been led to believe that I can request ADSM to pick files based on age.
If this is not true then I might have to write something which selects the
'day-5' files and sends these to tape directly.

The biggest problem (according to one IBM rep) is the number of filenames.
They felt that this number was so high that the ADSM inventory (index I
presume) would become a bottleneck and would impact both storing and
retreiving specific files.  I need to know if there is any validity to this
comment.  I could write something which puts multiple files into a tar file,
and then give that tar file to ADSM, however this is alot more work.

Regards, Chris
