Abstract: Methods, system, and non-transitory processor-readable storage medium for a policy proposal system are provided herein. An example method includes applying at least one policy to data stored on a storage system to identify matched data, where the matched data is data to be moved from the storage system to a secondary storage system. The policy proposal system identifies unmatched data stored on the storage system, where the unmatched data is data that is not identified as the data to be moved from the storage system to the secondary storage system. The policy proposal system trains a machine learning system with the matched data and the unmatched data. The policy proposal system predicts at least one new policy, where application of at least one new policy identifies at least a subset of the unmatched data to be moved from the storage system to the secondary storage system.
