A system and method for managing an electronic storage volume is
described. The method includes assigning a threshold to a constrained
storage space to define a first state in which an amount of data stored
in the constrained storage space exceeds the threshold and a second state
in which the amount of data stored in the confined storage space does not
exceed the threshold. The method also includes comparing the amount of
data to be stored in the constrained storage space and the threshold, and
performing a predefined action if the comparison indicates that the
amount data to be in the confined storage space would cause a transition
between the first state and the second state.
