What kind of multistreaming/multiplexing are you using, and what is your
target? I've gotten mailbox backup performance up to an "acceptable"
level (4 years ago I was at about 50 MB/s) by creating 28 simultaneous
mailbox streams, one for each letter of the alphabet (used * at the A-Z
level) and sending all of those to the same tape drive. I'll bet I
could get faster than that now.

you are seeing this speed doing brick level, or are you seeing it with
info store backups? ive never seen brick level go too fast on any type
of disk/net/tape drive combo (5.5/2000/2003). info stores go quite fast
in all cases (as expected).
aaarrrggghhh!!!!

We recently upgraded our storage on our Exchange 2003 cluster from a
locally attached Dell Powervault 220 to a HDS SAN solution and saw our
back times go from 8 hours to 45 minutes making no other changes. I'm
not sure exactly what our KB/sec was before, but we're seeing better
than 100MB/sec now over Gigabit Ether.

Im backing up Exchange 2003 Mailboxes through my LAN. Backup process
takes about 10 hours for about 200GB of data. Does anyone know what I
can do to drop it down.
