Abstract

Previous version data is copied to a location in a collection of snapshot data, wherein the collection of snapshot data represents a state of a protected data set at a baseline time associated with a snapshot. Once the previous version data has been copied to the location in the collection of snapshot data, an index is updated to associate the location in the collection of snapshot data with the previous version data. A data region storage location from which the previous version data was copied to the location in the collection of snapshot data is making available for reuse once the index has been updated.
