Abstract:
1. A method for dynamically managing data security of a first and a second plurality of files having first and second security levels, respectively, that include different remanence standards and compliance policies for various types of data, the method comprising the steps of: a computer system, responsive to a change in classification of a first file of the first plurality of files from the first security level to the second security level, wherein the first security level corresponds to a first data remanence standard and the second security level corresponds to a second data remanence standard, and wherein a high data remanence data block contains sensitive information which may require multiple re-writes to assure a secure delete; identifying current physical storage locations of respective files of the first and second pluralities of files and respective current data remanence standards of security levels for the respective files of the first and second pluralities of files, and relocating the first file from a current physical storage location, that was not clustered with the physical storage locations of the files of the second plurality of files, to another physical storage location which is clustered with the physical storage locations of the files of the second plurality of files, and wherein clustering files to consolidate multiple high remanence data blocks into a same physical storage location allows for a reduction in adjacent track re-writes.
