Abstract
Definitions are received for allowable activity windows and epochs. Each epoch specifies a retention duration and allowable activity window. There can be a retention policy specifying that copies created during a particular time period of the allowable activity window are to be retained past a retention duration of an initial epoch. A determination is made as to whether a copy was created during the particular time period specified in the retention policy. If the copy was not created during the particular time period, the retention duration of the initial epoch is added to a creation time of the copy to obtain a date after which the copy should be deleted. If the copy was created during the particular time period, a retention duration of a subsequent epoch is added to the creation time to obtain the date. The date is then associated with the copy.
