Data storage lineage system and method

A computer-implemented method comprising:

• storing, in a first data structure format, policy information for data history related to data of each resource of a plurality of resources;
• and
• storing, in a second data structure format, exception information related to the data history of the plurality of resources;
• wherein the first data structure and the second data structure store information sufficient to generate lineage information for any of the plurality of resources.

A computer-implemented method comprising:

• identifying policy information applicable to a compute resource within a specified time range, the policy information related to data management for the compute resource;
• generating, based on the identified policy information, a set of expected data management events for the compute resource within the specified time range;
• and
• modifying the set of expected data protection events based on information related to exceptions to the data management indicated by the policy information, wherein the modified set of data protection events provides lineage information for the compute resource.
