Each Buddy Space has a corresponding Free Space Map (FSM) File that defines the
space allocated within the Buddy Space. The FSM is also an unstructured Enscribe
file.
A collection of Buddy Spaces and their FSM Files is called a Buddy Set.
The diagram below shows the different length segments deployed in Buddy Spaces
which combine together to form a Buddy Set.
A collection of Buddy Sets is called a BuddyGroup.
The diagram below represents the number of Buddy Sets are deployed to form a
Buddy Group. A Buddy Group can access up to 99 Buddy Sets. There is no
limitation on the number of Buddy Groups than can be created.
