Abstract
A method is implemented in a computer infrastructure having computer executable code tangibly embodied on a computer readable storage medium having programming instructions. The programming instructions are operable to optimize data remanence over hybrid disk clusters using various storage technologies, determine one or more data storage technologies accessible by a file system, and determine secure delete rules for each of the one or more storage technologies accessible by the file system. The secure delete rules include a number of overwrites required for data to be securely deleted from each of the one or more storage technologies. The programming instructions are further operable to provide the secure delete rules to the file system upon a request for deletion of data for each of the one or more storage technologies a specific amount of times germane to secure delete data from the one or more storage technologies.
