Re: How effective is Doubletake or similar HA software with SBS?

The problem is that you can have additional DC's in a SBS environment,
but you can only have one SBS in that environment! DoubleTake will
work to replicate data, but only one of the boxes can be running SBS.

If you want a true replica of your SBS, you should look into installing
SBS in a virtual environment (either VMWARE Server or MS Virtual Server
2005 R2) and replicate the entire virtual machine. This gets around
the issue of only having one SBS because in fact you will only ever
have one SBS running at a time.

As far as licensing, you will need to check with MS, but I am guessing
you will only need one licence for SBS and 2 copies of Windows 2003 R2,
which allows you to run Virtual Server 2005 for free.

The big question is how much bandwidth does your ADSL support vs. the
rate of change on your virtual hard disk. Steeleye Data Replication
has a competitive solution to DoubleTake and we are optimized to work
in this environment.

I would be glad to discuss this with you further if you need additional
information.

Having recently suffered the horror of losing our SBS to mainboard failure
(power cut and spike that passed straight through the UPS...) I've been
instructed by my boss to look into HA systems.

Server is only 2 years old, and fortunately I was able to borrow an
identical box to transfer the drive array, but we were still without
access
to our data and mailboxes for 24 hours. Replacement parts are now on
order,
but without the spare box we would have been without it for weeks.

Ideally what we would like to do is mirror all the changed data between a
new server as the main box and the current repaired box in a remote
location
via ADSL. The thought then would be in the event of losing the first box
we
could collect the reserve and be up and running in about an hour.

Firstly would this be allowed under the SBS licensing, as one box is
effectively a cold reserve mirror, and perhaps more importantly would it
work?

As always, TIA.

Tom.
