Methods and systems for metadata tag inheritance for data tiering

Abstract:

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