Information Lifecycle Management (ILM), is a set of policies and procedures that govern the lifecycle of all corporate data. These policies and procedures once created are typically enforced by software or storage systems. The policies for ILM are different for each organization and they depend on industry/country-specific regulations. ILM policies help organizations dictate the lifecycle of data for the entire lifespan of the information. For example, a Human Resource transaction could reside on a production system for the first two years, then on an archival system for the next seven years, and on a long-term archive for the next 15 years, after which it may be destroyed. The notion of implementing ILM for data is to properly manage the data growth and move it along different tiers based on usage, regulatory, compliance, and storage requirements and eventually destroy data that is no longer required by the enterprise.
