ABSTRACT:
Techniques for time-dependent storage management with a portable application programming interface are disclosed. In one particular exemplary embodiment, the techniques may be realized as a method for time-dependent storage management. The method may comprise interfacing with a host and a storage system having one or more storage devices. The method may also comprise intercepting all write commands that the host issues to the storage system. The method may additionally comprise performing a copy-on-write operation for each intercepted write command, wherein copy-on-write data and metadata associated with each intercepted write command are recorded, the metadata including at least a timestamp associated with each intercepted write command.
