I used it for exactly that situation. The data transfer is real time and
I experienced no data loss in failover testing. The transition took less
than a minute (probably less than 30 seconds actually) with minimal
hassle reconnecting to the backup machine from the web server (we use
separate boxes for IIS and SQL obviously).
I looked at one or 2 other products and decided on Double Take bacuse it
was the only one that actually worked! I figured that was cause enough
to use it. The interface is easy to use, setup is pretty simple and data
transfer was quick (even the initial mirror of all data)

Subject: Re: has anyone used doubletake successfully?
I'd like to know if you've ever had to failover to the other server and
how quickly and smoothly, if at all that went?
Also, did you look at any other products or solutions before deciding on
Double Take and, if so, why did you decide on Double Take?
I understand that my situation may differ but I'm looking at using a web
server (IIS) and SQL 7.0 on NT or 2000 as the operating system (depends
on when the decisions are made) and data will need to be replicated and
if the primary server goes down there should be as quick and smooth as
possible a transition to the "backup" machine. I've had personal
experience with NT Cluster server and, for this application, the
failover takes too long. We are hoping to minimize transaction loss as
much as possible.
