Abstract
Disclosed herein are systems, methods, and non-transitory computer-readable storage media for a delayed secure deletion of files from a copy-on-write file system. A system configured to practice the method receives a change to a file, writes a copy of the file in a first block of a storage device, the copy including the change, determines whether the change meets a predetermined condition, adds an entry into a delayed secure deletion list when the change triggers the predetermined condition, the entry storing an address associated with the first block, and deletes the first block when another change to the file is received, wherein the another change triggers another predetermined event.
