You could attach forty 7 port USB hubs each with 8GB thumb drives in a
10d:1p RAID 5 configuration and simply copy the data. :-)))

Again this is not a TSM solution, but we use an EMC product to duplicate
disks.  As long as both disks are available to the system at the same
time take a look at OpenMigrater if you have access to EMC software.  It
does a block level copy while the system is up.  When it is done it
keeps the drives synced until a reboot replaces the old drive with the
new one.  We usually see about 20-30GB an hour.  We have done 10 million
+ file systems in just a few hours.

Well, it turns out that the client has no downtime for this system so I
don't think the image thing is an option. Not to mention one of the
admins installed the LVSA code through the GUI setup wizard the night
before and chose to reboot later and the system crashed with a bugcheck
for TSMLVSA.sys yesterday. IBM had multiple tickets where this had
occurred at other customers in their database. We are waiting on a
reasonable explanation from IBM but the client is not too comfortable
with the image idea at this point and is looking to use their old Backup
Exec system where they have been successful doing this in the past
(SHAME! SHAME!). I suggested the robocopy method to them but it is their
decision/data.

Thanks for all of your help!! Your are a great bunch of folks!!

If you assume a file create rate of about 100,000/hour then you are
looking at a 20 hour restore if all else goes well.  You might squeeze
more file creates out of your new server, but who really knows?  If you
assume a 200 GB/hour transfer rate and use image instead, you can cut
the restore time in half. You can't improve the file create rate by
using multiple streams.
In fact, that actually reduces the rate.

I'm still advocating the image route.

It is ~2,000,000 individual files after hours.
