Information lifecycle management (ILM) represents a major shift in creating and managing a storage infrastructure and its data. All data maintained on storage networks has a pre-defined lifecycle. The lifecycle identifies the way information is stored in an organization from its inception to its eventual archiving and removal. The objective of ILM is to effectively match specific information to the appropriate class of storage – primary, secondary, or tertiary – based on its assigned value. For example, high-value, frequently accessed data should be more accessible and stored on high-speed hard disks or even solid-state disks, whereas older data should be stored more cost-effectively on tape. The reliability and portability of tape ensures that older data can be easily archived and safely stored offsite.
