[Networker] Exchange backup crashes Exchange

I have an Exchange 2003 server running on a dual node active-passiveclustered MS 2003 environment. The backup server is NetWorker 7.4 SP1on a Sun T2000 with Solaris 10. The Exchange server is using theExchange 5.0 applications module for its backups and there are around600 users with around 400GB worth of data. Every once in a while, likemaybe once every two or three months, the daily IS full backup slowsdown to a crawl and eventually, it holds onto resources on theExchange server so long that it crashes Exchange. This, of course,pisses off our Exchange server's users, of which I am fortunately notone of them.

In researching this issue, I found nothing on PowerLink, but acolleague did find the following article on Microsoft's web site;however, it does not give any recommendations on how to fix theproblem as far as I can tell. I am not an Exchange user, nor am Iinvolved with managing our Exchange server so I am not in the bestposition to troubleshoot this issue. I have a case opened with EMC onthis problem, but EMC hasn't responded yet.


Here's the web page my colleague found ...

If this problem rings a bell with you, please let me know of anysuggestions on how to fix it.

Also, I am wondering if it would be better to abandon the use of theNetWorker Exchange module and use the VSS client to do Exchangebackups instead. If anyone has any experience using the VSS client forExchange backups, please let me know. In researching this backupproblem I found a white paper on using the new VSS client for Exchangebackups and it looks pretty interesting.
