How are you automating the restore? jeff e.

I will be automating the backup and restore w/ the software so I won't have to do anything other than checking just to make sure the data is ok.

Restoring to another server on a daily basis would be extremely expensive in terms of manpower at my organization. A DNS change might work for users (depends somewhat on network configuration) but it's not seamless since at a minimum the user would have to restart Outlook, and there's no way to automate server failover either. So if seamless and automatic are no longer requirements, the number of possible solutions and costs for implementation change dramatically. -- Chris Scharff, MVP-Exchange MessageOne Exchange Monitoring & Reporting: http://www.messageone.com/MV.asp Free Custom OWA Screens: http://www.messageone.com/m1owa/index.asp On 1/10/03 17:44, "Newsgroups" <[EMAIL PROTECTED]> wrote: So instead of a costly solution for us we may just restore to another server on a daily basis to minimize downtime. Now as for all the users, since they are pointing to that box, do you know if a simple DNS change to the new server would still work with outlook?

It's kind of hard to draw any conclusions from the SIS ratio alone. Kind of like the mailbox I exported to PST which was 60x larger in PST format than it was in the exchange DB.

It might be worth comparing the summed results of an mbinfo or mailbox resources export with the reported store size (less white space) to see if this really is the case on your servers especially the ones reporting 4. Let us know if you do!

I've had multi-year old servers that hover around 1.5, some that have stayed consistently over 4. What I find even more interesting is that I've started with many servers with an SIS of 1.0 - following an ExMerge based migration, and I've seen a steady increase in SIS over time, but I'll admit that they rarely get over 2-3 in those cases. Even at 1.5, a 30GB store is much smaller than the 45 that it would be otherwise. I'd call the benefit a mixture of both delivery speed improvements and disk storage space savings. ------------------------------------------------------ Roger D.
