Fastest Windows system backup software??

I am currently running Arcserve 6.61 and I have an Exabyte M2 drive. When I
backup my fastest fileserver with only source files selected (we are a
development shop), I get an average of 7 to 8 megabytes per second.

HOWEVER

We had a lot of activity on this particular server during the backup the
other day, and the server was pumping out 65 megabytes per second to my
client computer (amazing, eh?). With all the clients involved and the backup
running at the same time, this is an extremely random access pattern too.

Obviously, the Arcserve agent is a stupid single threaded process and it is
a MAJOR limitation. It is a big improvement over using regular SMB
transfers, but it isn't even close to being capable of using the potential
of the server.

People say the fileservers are the limitation, not the tape drives. But it
looks to me like the backup software is the limitation, since my server can
spit out data faster than any current drive can handle (again, even with a
random access pattern).

Does anyone know of backup software that will take better advantage of my
hardware? I'm guessing it would have to have a multithreaded client that can
request data of more than one file at the same time, or have two jobs
backing up two different datasets on the same server at the same time.

Anyone?
