Abstract:
1. A method implemented in a computer infrastructure configured to determine a plurality of data storage technologies accessible by a file system; determine secure delete rules for each of the plurality of storage technologies accessible by the file system, wherein the secure delete rules include a number of overwrites required for data to be securely deleted from each of the plurality of storage technologies; provide the secure delete rules to the file system upon a request for deletion of the data so that the file system need only overwrite the data for each of the plurality of storage technologies a specific number of times germane to securely delete the data from the plurality of storage technologies; and optimize data deletion of a file striped over a hybrid storage system by overwriting data corresponding to the file on a first storage device a predetermined number of times and overwriting the corresponding data on a second storage device a different number of times.
