Well first of all data is located on the local exchange machine. Backups are
running on gigabit Ethernet and the max KBps I get is around 6400. The policy
setup is using MS Exchange and I selected MS EXCHANGE MAILBOX from the
directives set. I don't know what recovery storage groups are since im not
responsible for exchange and if my exchange guy knew about it he should've told
me bit I guess he doesn't. what can I do with that?
Currently I have no SAN. We are still in the process of evaluating what we
need. It takes almost 11 hours to backup my full mailbox store. Info_Store
backups are fast at around 40MBps. I have no mutliplexing/multistreaming
configured on this policy. Would it make a difference for exchange? If so, what
should the settings be given I have a Hp MSL6060 Tape Lib with to LTO3 drives?

Well that makes more sense, because I have never, ever seen any performance
increase of BLB regardless of the hardware involved, the spindles involved,
fiber, tape technology. And the originator was specifically asking about the
backup type "BLB".
BLB are slow, slow slow! and should be avoided - as I pointed out in an earlier
thread, Ex2k3 offers ALOT more functionaility for you to move away from this
type of backup.

I'd tell you I've got the magic voodoo over here Paul, but then you'd
want it. And If I'm gonna give up the goods I'd better get dinner and dancing
first. =P
Our Exchange Fulls running by themselves over GigE to a DSSU sitting
around doing nothing else does about 100MB/sec, until it hits the logs. Even
then, its very fast but the average time rounds out to 80MB/sec, still
respectable. My fastest backup until that point was a Redhat 3 / Oracle 9
Database at 55MB/sec (give or take Archive logs.) In my Exchange case, the
secret has been number of spindles and drive speeds on the SAN. We did serious
I/O testing on the Exchange server's storage and went for performance all the
way. I think each storage group and logs are their own 8 disk raid5 w/ 146GB
15K FC drives in a Hitatchi SAN. Surprisingly, I got a Sun StorEdge 5320
running remote NDMP backups to LTO3 at 100MB/sec first try, yesterday! That
was purely test data, and it remains to be seen if it will maintain that after
we load up terabytes of data. (I don't manage the SAN or the NAS, so all my
secret sauce is definitely someone else's.)
I haven't done a brick level backup of Exchange since I learned about
Recovery Storage Groups, and that was on Arcserve, or whatever it was called
before CA bought it. That was the 90's and all my memories from the 90's are
bad, so lets not go there. I have to admit I've never run BSD. Sounds like
fun, and the devil logo has definitely got it going on! Silly penguin.

I've never seen 100MB/s, let alone "better than" 100MB/s on a single
GigE link, for ANY client type, let alone Windows, or Exchange, so colour me
surprised.

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!!!!
