Really? Perhaps we are talking about 2 different things. VSS is included with Win2003. Other than the cost of the OS, which would be incurred whether you used VSS or not, there is no cost for VSS separately.
As for the second issue, if there were not an issue with VSS and resource intensive systems, there would not be an MS official patch to address the problem and extend the time outs. As for the third issue, there are articles at both MS and Veritas explaining why it is not the best solution for backing up a database. No, I don't remember off the top of my head what the article numbers are, I found them doing a search on the VSS in both KBs. If you think about how it works, it doesn't seem too hard to me to figure it is not the best backup solution for a DB.

I spent quite a bit of time talking with the Exchange product group about this in both Redmond and at TechEd and got a different feel from those discussions. While VSS is not everything some people like to believe it might be and the costs associated with it can be quite significant, I got no indication from them that my investment would not be a good one should I decide to invest in such a solution. What about the process in and of itself is not resource or restore friendly assuming properly sized and managed hardware? -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Dan Bartley Posted At: Thursday, June 24, 2004 1:46 PM Posted To: swynk Conversation: Shadow Copying of Exchange 2003 Subject: RE: Shadow Copying of Exchange 2003 While they do say it can be used for Exchange and SQL, and indeed you will see them in the shadow components that can be backed up, they do not recommend it as the best method. It is not as resource friendly nor restore friendly (logs, etc.) as other more refined database backup software. In fact if you have a very resource intensive system and try to backup DBs with Shadow Copy it is likely to fail without a MS patch that increases the timeouts (that answers your question on whether it is faster). It is however very effective on other system objects like registry and AD DB.

Yes, you are right....this is the theory...but only a theory at this point..haven't seen it done in the "real world". -----Original Message----- From: Jason Clishe [mailto:[EMAIL PROTECTED] Sent: Thursday, June 24, 2004 12:19 PM To: Exchange Discussions Cc: Jason Clishe Subject: RE: Shadow Copying of Exchange 2003 This is absolutely not true.

The shadow copying feature in Windows 2003 is for the OS not for a database. To be clearer, you can use shadow copy for Windows or the OS not for the Exchange database. Hope this makes sense. We were in the same thought pattern as you and learned this wasn't going to work. Samantha -----Original Message----- From: Ajay Kulsh [mailto:[EMAIL PROTECTED] Sent: Wednesday, June 23, 2004 8:42 PM To: Exchange Discussions Subject: Shadow Copying of Exchange 2003 I need some enlightenment regarding Shadow Copying of Exchange 2003. I have read MS article - 822896 and some other references to understand shadow copying. What is not clear to me that if it takes typically only *about a minute* to create a shadow copy, how long does it normally take to write this data to a backup hardware? And while backup program is writing this, where is data kept? Memory cannot keep so much and I don't see any hard drive space requirements mentioned. Can shadow copying of Exchange 2003 only work with backup like SAN, not normal tape drive?
