SearchCIO.com published a well written article on Data Lifecycle Management today. The article included archiving as a means to a successful DLM plan. HSM (Hierarchical Storage Management) is only part of the picture in DLM. Archiving must play a key role.
Archiving not only provides the management of the data but also indexes and stores the data in an efficient manner that HSM systems can benefit from. Typically archiving systems can store a single instance of data that is duplicated across emails systems, file systems, SharePoint and other systems from which data is archived. By storing only a single copy the document the storage needs for the HSM system are greatly reduced.
How does this fit into DLM? Storing the data is efficiently is only half of the story. Managing the data by applying retention across all data sets uniformly ensures that data that is at the end of the lifecycle is removed. It also ensures that data that needs to be kept for legal discovery purposes gets kept.
The article is a great read and includes information about the cost savings realized from storing data more efficiently thanks in part to archiving solutions.
