I understand that there may be some limitations to the Exchange API but I am
not using this. I have shutdown all Exchange services and I am backing up
the database offline using TSM BA client 5.1 and I still see the same
performance of 8mb/sec. So in this case I am simply copying the file as flat
file. I would expect better performance than this. Any ideas?

Thanks

Exchange is not a file level backup.  It is more like a database unload.
The Microsoft Exchange Backup API is only designed for 30GB/hr.  Funny, that
figures out to 8.33MB/sec.  However, on much faster servers with FC disk I
have seen a little faster than this.

Subject: Exchange file performance


Hi All,

I am running TSM server 5.1.0.0, TSM BA Client 5.1.0.1, TDP for Exchange
2.2.0.0 and Exchange 2000. I noticed that when I backup the exchange
database using TDP or BA client I only get approximately 8mb/sec aggregate.
So I created a file of the same size, 1.4gb, and I got 25mb/sec aggregate. 

Has anyone encountered a performance difference such this when backing up
Exchange files?
