Methods and systems for metadata tag inheritance between multiple storage systems

Systems and methods for metadata tag inheritance are disclosed. The methods include maintaining a plurality of data storage systems in communication with an external metadata management system, operating the metadata management system to store metadata corresponding to data residing on the data storage systems as a plurality of entries, detecting an execution of a data operation command on data residing in a data storage system that causes movement of a data set from that data storage system to a destination data storage system that is different from that data storage system, and operating the metadata management system to create a new metadata entry corresponding to the execution of the data operation command. Each of the plurality of entries may include one or more custom tags, and the new metadata entry may include at least one custom tag created before the execution of the data operation command.
