I am at a site now that has a very complicated internal security layout. There are are large number of cells of servers in isolated firewalled "rooms" with their own MA.
It can be difficult to remember which MA to use to backup a particular server. The server names are not very descriptive.
My thought is to extend the Client Computer Group section in our GUI so that a user can easily tell that one of the servers in the group is an MA.
Maybe a sub-tree would work, or perhaps alter the server icon slightly. We already alter the icon if a server does not have the file system iDA installed on it, there is a small triangle with a ! in it. Also we alter the icon if the server is a cluster VM. We turn the icon yellow in that case.
If we were to alter the icon if the server has the MA installed on it that might do the job.
However given the choice a sub-tree in the client computer group would be the most usable option that I can think of.
