Abstract
An apparatus comprises a processing device configured to generate a tree structure characterizing relationships between storage objects in a storage system represented as logical page nodes specifying respective logical page addresses, arrays of pointers to other logical page addresses, snapshot group identifiers, and logical extent offsets. The processing device is also configured to traverse the generated tree structure to identify (i) a given logical page node specifying a given logical page address, snapshot group identifier and logical extent offset from a query and (ii) other ones of the logical page nodes that specify the given snapshot group identifier and logical extent offset and comprise a pointer to the given logical page address in its associated array of pointers. The processing device is further configured to provide a response to the query specifying the given logical page node and the identified other ones of the logical page nodes.
