Im also running Ex2K3 and have about 900 mailboxes. The slowness is killing my backup window since it takes 11 hours. I'm looking into Quest Recovery Manger now. So you don't use NBU for your mailboxes at all?? Also should I be running multistreaming?

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? ________________________________ From: [EMAIL PROTECTED] on behalf of WEAVER, Simon (external) Sent: Thu 5/10/2007 11:20 PM To: 'Martin, Jonathan'; Paul Keating; [email protected] Subject: Re: [Veritas-bu] Exchange Mailbox Backup Jonathan wrote: I haven't done a brick level backup of Exchange since I learned about Recovery Storage Groups 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.

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. -Jonathan ________________________________ From: Paul Keating [mailto:[EMAIL PROTECTED] Sent: Thursday, May 10, 2007 3:26 PM To: K Chapman; Martin, Jonathan; Anas Kayal; [email protected] Subject: RE: [Veritas-bu] Exchange Mailbox Backup 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. :o) -- -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of K Chapman Sent: May 10, 2007 3:22 PM To: Martin, Jonathan; Anas Kayal; [email protected] Subject: Re: [Veritas-bu] Exchange Mailbox Backup 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!!!!
