Abstract

Maintaining a generation value for each fileset that is distinct from a corresponding fileset manager preserves the independence of nodes while also allowing distributed fileset management. A fileset manager can maintain a value that reflects consistency snapshots for that node (“node generation”) separately from a value that reflects consistency snapshots for a particular fileset (“fileset generation”).
