Abstract
A first entropy indicator is calculated at a first time for a collection of data stored in at least one memory. A second entropy indicator is calculated at a second time for the collection of data. The first entropy indicator is compared with the second entropy indicator. Based on the comparison, it is determined whether to back up the collection of data and/or whether to retain an earlier backup of the collection of data.
