One embodiment is a method and apparatus for modifying retention periods in a storage system, in which previously defined retention periods for units of data may be reduced. In another embodiment, the retention period of a unit of data may be modified in response to the occurrence of an event by renewing previously defined retention periods until the occurrence of the event is detected. If the occurrence of the event is detected, a retention period associated with that event may be established for the unit of data. In yet another embodiment, retention classes are used to define retention periods for units of data so that the retention period of a unit of data may be modified without modifying the unit of data itself. In a further embodiment, a request to the storage system to reduce a retention period includes authentication information that the storage system may use to verify the request.
A method of processing data in a computer system comprising at least one host and at least one storage system, the method comprising acts of:
At least one computer readable medium encoded with instructions that, when executed on a computer system, perform a method of processing data, the computer system comprising at least one host and at least one storage system, the method comprising acts of:
A storage system for use in a computer system, including the storage system and at least one host, the storage system comprising:
A method of processing data in a computer system comprising at least one host and at least one storage system, wherein the at least one storage system stores a unit of data having a previously defined retention period during which the at least one unit of data is to be retained on the at least one storage system, the method comprising acts of:
At least one computer readable medium encoded with instructions that, when executed on a computer system, perform a method of processing data, the computer system comprising at least one host and at least one storage system, wherein the at least one storage system stores a unit of data having a previously defined retention period during which the at least one unit of data is to be retained on the at least one storage system, the method comprising acts of:
A host computer for use in a computer system that includes the host computer and at least one storage system that stores, for the host computer, a unit of data having a previously defined retention period during which the at least one unit of data is to be retained on the at least one storage system, the host computer comprising:
