Methods and systems for metadata tag inheritance between multiple storage systems

A computer-executed method comprising:

• maintaining a plurality of data storage systems for storing electronic data, each of the plurality of data storage systems having one or more processors having circuits and logic for processing information and performing logic operations;
• maintaining an external metadata management system separate from and in communication with the plurality of data storage systems, wherein the metadata management system has one or more processors having circuitry and logic for processing information and performing logic operations;
• operating the metadata management system to collect and store metadata corresponding to all the electronic data residing on the plurality of data storage systems as a plurality of metadata entries in the metadata management system, wherein each of the plurality of metadata entries in the metadata management system comprises metadata, wherein operating the metadata management system comprises applying one or more custom metadata tags by the metadata management system to each metadata entry in the metadata system, wherein applying the one or more custom metadata tags to each metadata entry comprises analyzing the metadata in a respective metadata entry to derive the one or more custom metadata tags to apply to the respective metadata entry, and the one or more custom metadata tags are associated with and related to the metadata in the metadata entry;
• detecting execution of a data operation command on a data set of the electronic data residing in at least one data storage system of the plurality of data storage systems that causes movement of the data set from the at least one data storage system to a destination data storage system that is different from the at least one data storage system, wherein the destination data storage system has one or more processors having circuitry and logic for processing information and performing logic operations;
• and
• in response to detecting the execution of the data operation command, creating, by the metadata management system, a new metadata entry in the metadata management system corresponding to the execution of the data operation command, wherein the new metadata entry includes applying at least one custom metadata tag to the new metadata entry before execution of the data operation command.
