A storage system includes a storage pool (200) with at least one storage media (210, 220, 230) and storage management, wherein the storage management stores a received new data object in the at least one storage media (210, 220, 230) of the storage pool (200); wherein the storage management comprises an analytic engine (300) analyzing the new data object based on content of the new data object; wherein the analytic engine (300) comprises a classification component (310) classifying the new data object into predefined data object type classes (312, 314, 316, 318, e.g. picture, text, audio, video); a grouping component (320) creating a data object specific grouping vector for the new data object, which comprises at least one content related scalar (e.g. time of picture, number of people in picture, persons in picture), and grouping data objects of a corresponding type class (312, 314, 316, 318) in different data object groups (322, 324, 326) based on corresponding grouping vectors of the data objects (e.g. part match); and a ranking component (330) ranking the data objects of a corresponding data object group (322, 324, 326) based on a data object specific ranking vector comprising at least one quality scalar (e.g. sharpness of picture etc) for each data object group (322, 324, 326). The ranking results may be used to execute migration policies. |
