i have 4 server enterprise 2008. two are active and two failover. i will be using double take as the replication/failover software.

i am installing sql standard 2005, kofax scanning software, records management software, and a release script, and backup exec

will double take be able to replicate everything or do i have to purchase two of each of the software licenses?

I've used it on an SBS server.  The whole point to the server is to completely replicate the server that it was on from a software standpoint.  So, it SHOULD.  But I will say it's VERY UNWISE to implement without running tests and a demo first.  DoubleTake offers a 14 day demo - I strongly recommend you use it and experiment for yourself.  For me, the failover was NOT instant.  Depending on your configuration, you may be MUCH better off using a cluster or VMs in a cluster instead.

even though it wasnt instant, did everything replicate? was there any data loss?

No data loss that was detected... but it then required a complete rebuild of the "failed" server. A straight cluster can prevent interruption caused by patching and reboots - DoubleTake cannot.

And when I say not instant - I mean it took close to 60 minutes to complete.

When it "fails over" it completely takes over as the old server.  If you just boot the old server back up, then you have two identical servers - right down to the name - on the same network - this would create HUGE problems.  So you would have to rebuild the server, install DoubleTake, fail things BACK, then rebuilt the second server (assuming the hardware was not otherwise equal; at my client they are using their old server as a backup so they wouldn't want to run for any length of time on the old hardware - it's purely a backup system.

(By the way, I'm assuming you would be using the full server failover that completely mirrors the system).
