Information Lifecycle Management (sometimes abbreviated ILM) refers to a wide-ranging set of strategies for administering storage systems on computing devices. ILM is the practice of applying certain policies to effective information management. This practice has been used by Records and Information Management (RIM) Professionals for over three decades and had its basis in the management of information in paper or other physical forms (microfilm, negatives, photographs, audio or video recordings and other assets). ILM includes every phase of a "record" from its beginning to its end. And while it is generally applied to information that rises to the classic definition of a record (Records management), it applies to any and all informational assets. During its existence, information can become a record by being identified as documenting a business transaction or as satisfying a business need. In this sense ILM has been part of the overall approach of ECM Enterprise content management. However, in a more general perspective the term "business" must be taken in a broad sense, and not forcibly tied to direct commercial or enterprise contexts. While most records are thought of as having a relationship to enterprise business, not all do. Much recorded information serves to document an event or a critical point in history. Examples of these are birth, death, medical/health and educational records. e-Science, for example, is an emerging area where ILM has become relevant. In the year 2004, the Storage Networking Industry Association, on behalf of the information technology (IT) and information storage industries, attempted to assign a new broader definition to Information Lifecycle Management (ILM). The oft-quoted definition that it released that October at the Storage Networking World conference in Orlando, Florida, stated that "ILM the policies, processes, practices, and tools used to align the business value of information with the most appropriate and cost effective IT infrastructure from the time information is conceived through its final disposition."〔As cited in: Francis, Bob. "SNIA nails down ILM definition." ''InfoWorld''. 1 November 2004: 14.〕 In this view, information is aligned with business processes through management policies and service levels associated with applications, metadata, information, and data. ==Policy== ILM policy consists of the overarching storage and information policies that drive management processes. Policies are dictated by business goals and drivers. Therefore, policies generally tie into a framework of overall IT governance and management; change control processes; requirements for system availability and recovery times; and service level agreements (SLAs). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Information Lifecycle Management」の詳細全文を読む スポンサード リンク
