Abstract
An information processing system comprises a plurality of front-end storage tiers, a plurality of back-end storage tiers, a plurality of data mover modules arranged between the front-end and back-end file storage tiers, and a metadata warehouse associated with the data mover modules and the front-end and back-end storage tiers. The data mover modules are configured to control movement of data between the storage tiers. The metadata warehouse is configured to store for each of a plurality of data items corresponding metadata comprising movement information characterizing movement of the data item between the storage tiers. The movement information for a given data item illustratively comprises locations, timestamps and checksums for different stages of movement of the given data item. Other types of metadata for the given data item illustratively include lineage information, access history information and compliance information.
