An approach is disclosed for placing data on volumes. Accesses to data entries at a source location are analyzed to determine locations of the data entries in one or more files. Types of data are identified at the one or more data entries. Types of accesses are identified for the data entries. Durations of the types of accesses to the data entries are identified. An access value is calculated by mapping the one or more types of data combined with the one or more types of accesses combined with the one or more durations of the types of accesses. Confidential sensitive data is moved according to the calculated access value, where a highly accessed confidential data is separated from lighted accessed confidential data by moving a selected portion of data from the source location to the destination location.
