A method for managing a long-running process carried out upon a plurality
of disks is disclosed. A registry is established, the registry having a
plurality of entries, each entry corresponding to one of the plurality of
disks, each entry having a value indicative of a respective time at which
its corresponding disk was last acted-upon by the long-running process.
The long-running process executes on each of the disks based upon an
order in which the disk having an oldest last acted-upon time is
processed first and the disk having the newest last acted-upon time is
processed last.
