In one embodiment, a method includes receiving a query related to a first data extent. The method also includes determining whether the first data extent is eligible for deletion based on a first sliding window time period equal to a predetermined retention period added to a predetermined deletion cushion in response to the query requesting a deletion operation for the first data extent. The method also includes determining whether the first data extent is eligible for linkage based on a second sliding window time period equal to the retention period less a predetermined linkage cushion in response to the query requesting a linkage operation for the first data extent.
