configuring Kolab for multiple hosts means that you spread your users
of several hosts. Still each user will be only present on one host and
only this machine will hold the users e-mail. So this basically
load-balancing and not replication which is what you would like to
have.

Right now there is no integrated solution for automatic replication of
a Kolab server. You might be able to create your own solution by
following the backup guide at

Cheers,

Gunnar
