[cisco-voip] backup strategy - pub and tftp? (V7)

[Ed Leatherman]

I'm totally guessing here, but maybe its partly to cover any MOH or
other files you have on the particular server, and partly to make sure
the database keys already all match up so there is less work on the
pub wrt db replication. If you added the sub as a new server, wouldn't
that cause a lot of updates across the cluster when you go to add it
back into a CM group, mrg, etc?
