Abstract
An extent-based storage architecture is implemented by a storage server. The storage server generates a new extent identifier for cloning a source extent identified by a source extent identifier and stored at a source data structure that includes a length value providing a length of the source extent, an offset value and a reference count value that provides a number of data containers that reference the source extent identifier. The storage server updates a data structure for a cloned version of the data container for storing the new extent identifier that points to the source extent identifier and includes an extent length value and offset value different from length value and the offset value of the source data structure.
