Abstract
A processing system manages an ordered set of hierarchical data structures representing snapshots that define the state of a filesystem at different points in time. The data structures include nodes that store strong references, which can be utilized to read or write data, or weak references that can be only utilized to read data. In order to create a new snapshot, a root node is created for a new data structure representing the new snapshot by copying the root node of the data structure representing an active view of the filesystem. Any strong references stored in the copy of the root node are then changed to weak references. Snapshotting operations can then be performed with respect to the new snapshot utilizing the weak references stored in the root node of the new data structure.
