We use DoubleTake on a number of DAS based File/Print servers in our distributed environment that are fairly large (~1 TB). We implemented it when we had some server failures that created extended outages for clients while we recovered data from backup tapes. Our current implementation is locally across a dedicated NIC to a "stand by" server that can take over if we lose the primary. In our configuration and failover or failback is a manually initiated process.
It seems to work pretty well but there are some limitations. We briefly considered using it for Exchange and it may work for smaller environments but I was not comfortable using it in a medium or large exchange shop. I can't speak to SQL. Bottom line, It seems to work well for File servers but I would not go farther than that. There seems to be better ways of addressing the other systems. We are taking a close look at FRS that is in R2. We are hoping that MS got it right this time... ;-) Diane -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Kern, Tom Sent: Wednesday, July 06, 2005 11:07 AM To: ActiveDir (E-mail) Subject: [ActiveDir] Doubletake(OT) Anyone using Doubletake out there? My manager is interested in purchasing it and I was wondering what you guys think of it, yea or nay. In my enviorment it doesn't seem to make sense except as to file servers. DC's have built in redundancy if you have more than 1 and we have an active/passive exchange2k3 cluster plus with RSG and/or dial tone restore, it doesn't seem to apply here as well. For MS SQL we are using a log shipping solution. So i was just wondering if any one out there had experience with this or a simillar product and how they are using it and if its worth it to get. Thanks a lot.
