A storage management subsystem monitors usage of the data stored by a data storage system. Based at least in part on the monitored usage of the stored data, a storage profile is determined for the stored data. The storage profile indicates a first time period during which a first portion of the stored data is anticipated to be accessed and a second portion of the stored data is not anticipated to be accessed and a second time period during which the first portion of the stored data is not anticipated to be accessed. During at least the first time period, the first portion of the data is stored in a decompressed format and the second portion of the data is stored in a compressed format. During at least the second time period, the first portion of the data is stored in the compressed format.
