Method for selectively performing a secure data erase to ensure timely erasure

摘要

A method and computer program product are provided to ensure a timely secure data erase by determining an erasure deadline for each physical volume of a plurality of physical volumes and calculating a remaining time for each physical volume. The remaining time is calculated for each physical volume by comparing a current date to the erasure deadline of each physical volume respectively. The physical volumes may then be sorted based on the remaining time and the physical volume with a shortest calculated remaining time will be selectively secure data erased.

1. A method comprising:
determining an erasure deadline for at least two physical volumes of a plurality of physical volumes; calculating a remaining time for each said physical volume by comparing a current date to said erasure deadline of each said physical volume, respectively; and performing a secure data erase on said plurality of physical volumes prior to the respective erasure deadline of each said physical volume in an order based on said calculated remaining time, wherein said secure data erase is performed on said physical volume with a shortest calculated remaining time until the erasure deadline first.
