Rolf,
I am sure the tape library can handle the data load. Where most
problems happen is in the communications between the data centers.
If your data centers are 200KM apart and connected by a 1Gbps link,
your bottleneck is the WAN link due to latency, cost and competition
with other data

This is absolutely correct, especially ifyour datacenters are DR sites

A way to do this without shipping tape is to use a deduplication target.
Backup to a local dedupe
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 tim
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

I've seen restores of 1+M files take days due to the delays associated with
general system over head (creating directory entries, etc...) and by days I
mean 5-7+.
And so again, I'll mention...
Just because you CAN put a million or more files on a single drive doesn't
mean it's a good idea!

Amen to Dwight's comment! And can you imagine a filespace with 10M files? I
shudder...

The only practical way to do this is via replication. I believe there
are some products out there for Windows and Linux that are software
based. Just set it up, wait for it to finish. Verify it is fully
synched and cut over to the new replica.

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

Whatever you can do or believe you can, begin it.
Boldness has genius, power and magic.
What about an incremental or asynchronous restore (or whatever we may
want to call it)...
The file space may have 2TB but how much of it is changing every day ?
5%, 10 %, 15% ?
I Would try the following:

Would you be so kind as to share your stories about why restores fail, when
they do?
We are working on a way to prevent such failures.
(Our whitepaper is at http://www.tsmworks.com/downloads/art-whitepaper.pdf, if
you're curious.)
Your real-world anecdotes are helpful!

The product looks intriguing. The paper did not address my biggest problem,
restoring the Windows OS. Our issue is verifying the SP level of the server
prior to restore. We have had very little success restoring the OS if the
target OS is a different SP level than the backup.

We have some users who are (ab)using TSM to back up network drives that
they have mapped. I want to stop this, via something in a Client Option
Set. How would I go about coding such a blanket exclusion, when I don't
know what the name of the system hosting the drive, or its drive letter,
might be?
