I need to move a few million files (~600GB) from one server to another.

The originating server is running 2k3 Storage Server Edition and the destination server is running 2k8 Enterprise. Both servers are using 4 disks in RAID 5.

Here's what I've tried:

* Robocopy: Seemed really slow. Like took 30 minutes to move a gigabyte.

* RichCopy: Nice and fast, except it didn't preserve ACLs. That's the most important thing. I need permissions preserved.

* Fast Copy: It seems to work. It's about the same as Robocopy. Maybe faster. I can't tell.

The main problem with everything is the number of files. They're not large, there are just a ton of them. (Think millions of Word docs and other similar files.)

The other problem is that there's a backup job running right now. (It's been running for over 30 hrs.) I'd need to get permission to kill it.

What do you guys think.

Fast Copy seems to be about twice as fast as robocopy. However, it's all still too slow.

Does anyone know of a multithreaded file copier. I think that's the main problem. I really don't want to write one.

You will want to kill that backup process as it uses a lot of cpu cycles
and hard drive throughput.
That is going to slow it down a lot.
Still,600Gb is a lot to move and will take a while.
You might dump the files to an external drive,then
transfer them.
