Various embodiments for managing data in a data storage having data deduplication. A back reference data structure is configured for user data segments as a mechanism to identify an affected storage block to which information in the back reference data structure refers. The back reference data structure is initialized such that a resolution of the back reference data structure diminishes as a number of the user data segments referencing the affected storage block increases.
