Thanks, It looks as though a local guy replaced the external tape drive and 
never restarted the system. A system restart with new drive seemed to clear 
things up. Nice to be informed!

It was odd though that all other backup sessions ran at top speed but a faulty 
SDLT would cause just the bricks to slow down to a snails pace. We now have 
gone from 6mb/min to 75mb/min for bricks backups as of last evenings backups. 
Its still a little slower than other similar field offices but gets done before 
morning. We normally only run this on Friday evenings due to the long times 
bricks can take. We will be looking to do db maintenance soon to see if this 
brings us back normal speed.

The Brick-Level backup scans the entire Exchange Information store (IS),
enumerates each mailbox, and then each individual message, and associated
attachments.

This results in backup times that are significantly slower than an IS backup,
which is backing up the whole database, and not enumerating individual
objects within it.
 
If your backup is unable to complete in the allotted time you may wish to
consider backing up just those mailboxes which are most important, or those
that perhaps are most likely to require a restore.

----I am currently utilizing the Deleted Item Recovery and Deleted Mailbox
Recovery and only doing brick-level backup on the weekend.

The database may need a defrag, or there's antivirus software making the
backup extremely slow.

We are running Exchange 2003 SP1 on Windows 2003. We have one field office
server that the bricks level backups are running very slow. At about 6mb/min.
We are using ArcServe 11.1 with the Exchange agent. We have this
configuration in 40 other offices and get around 100mb/min with bricks. All
systems have single SDLT drives connected to them. 

This particular site had the tape unit replaced and still the same slow
speeds on bricks only backups. DB backups run at over 1gb/min.


Could this be an issue with the Exchange database needing maintenance or a
virus software issue?

Any suggestions appreciated. 

Thanks
