A method and system for shredding data within a data storage subsystem is
disclosed. According to one embodiment, a method is provided of
continually shredding data within a data storage subsystem in which all
the data of a first storage element is made permanently unreadable
followed by the performance of a data shred process. In the described
data shred process, second storage element is first selected (e.g., from
plurality of candidate or potential storage elements), which includes a
first storage object to be preserved and a second storage object to be
shredded. Once the second storage element is selected, data of the first
storage object is stored/copied within the first storage element.
Thereafter, all data of the second storage element is rendered
permanently unreadable.
