Abstract:
Methods and systems for improving performance in a storage system utilizing snapshots are disclosed by using metadata management of snapshot data. Specifically, various metadata structures associated with snapshots are utilized to reduce the number of IO operations required to locate data within any specific snapshot. The number of IO operations are reduced by allowing the various metadata structures associated with the temporally current snapshot to locate data directly within any temporally earlier snapshot or on the original root volume.
