All of the group and server information is stored on the local machine for each user. When you close the Replication Console, the group information is saved and will be persisted the next time you open the Replication Console on this machine. If you want to share the group configuration with another user or machine, you can export the group configuration information (File, Export server group configuration) to an .xml file which is saved to the same directory where Double-Take Availability is installed. That file can then be copied and imported (File, Import server group configuration) by another user on this machine or to another machine.
