Claim:
1. A computer-implemented method for managing a partial release for a unit of storage space in a storage system, the method comprising: establishing an invocation threshold for initiating a partial release for a unit of storage space; establishing a preservation threshold for releasing a fractional amount of the unit of storage space, wherein the fractional amount includes a fractional numeric value that represents a second unused space measurement of the data set, wherein the second unused space measurement of the data set is an amount of space that is to be removed in a complete execution of the partial release, wherein the preservation threshold includes a numeric value that represents a third unused space measurement of the data set, wherein the third unused space measurement of the data set is an amount of space that is to remain after a complete execution of the partial release, and wherein the preservation threshold added to the fractional amount is equivalent to the unused space measurement of the data set; initiating, in response to reaching the invocation threshold, the partial release; and releasing, in response to initiating the partial release, the fractional amount based on the preservation threshold.
