Recovery is typically end-user driven and is either provided through an extension to the file system

Chapter Three discusses the knowledge prerequisite to file system
development by presenting a seven-step systems analysis process to be applied in the subsequent chapters.
Each instance of these file systems
is typically limited to 2TB of capacity.
