Abstract
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. A secure data erase is performed on the plurality of physical volumes in an order based on the calculated remaining time, where the secure data erase is performed on the physical volume with a shortest calculated remaining time first.
Claims18
A computer-implemented 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 said erasure deadline 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 first.
A computer program product comprising a non-transitory computer readable storage medium comprising:
- a computer readable program wherein said computer readable program when executed on a computer causes the computer to:
- determine an erasure deadline for at least two physical volumes of a plurality of physical volumes;
- calculate a remaining time for each said physical volume by comparing a current date to said erasure deadline of each said physical volume, respectively, the erasure deadline of each physical volume being later than said current date;
- and
- selectively perform a secure data erase on said plurality of physical volumes 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 first.
