Four hours per platter is about what I get with CPY when I issue CPY for
each file on the platter. I have a database table that has a record for
each file on the platter. I have an application that sorts the records
by optical path and issues CPY for each one.

Subject: Re: Alternative to CPY for Optical
I had a project last year to transfer ninety platters to DASD and ran up
against the same problem with the CPY command. The fastest solution by
far was to do an automated FTP transfer. Platters that took a full day
using CPY ran in a blazingly fast(!) four hours using FTP.
One caveat: FTP will not create subdirectories automatically, so you
have to dump the directory tree structure first and then build your FTP
script with the necessary MD commands in it. I'd be happy to share the
script programs with you off-list if you're interested.

Hi,
I need a way to copy images from a 3595 Optical drive (think it's
3595...the model numbers do not stick in my head) to DASD.
I've been using they CPY command like this:
CPY OBJ('qopt/F0105A/*') TODIR('/newdir') SUBTREE(*ALL) REPLACE(*YES)
And this works, but it's really slow. It can take, literally, days to
copy a single platter of data.
Is there another method, even commercial, that someone can point me
to, that would allow me to perform this copy faster?
I've got something like 140 platters to copy and a small time window
to get it completed in.
Thanks!
