Managing the life cycles of backups

Introduction
Years ago, we treated all data as equal. All data originated on one type of storage and stayed there until it was deleted. We now understand that not all data is created equal. Some types of data are more important than others, or accessed more frequently than others. Data life cycle management (DLM), a component of information life cycle management (ILM), defines the DLM concept where data is created on one storage system, then migrated to, usually, less expensive storage systems as it ages.

Implementing tiered storage allows IT organizations to better utilize their existing storage. But, many who understand the benefits of implementing data life cycle management within their environments do not take the concept far enough into the backup space. They assume that data is backed up to some media, be it tape, disk or optical, and that is its final resting place.

However, backup data has its own lifecycle and it needs to be managed to maximize IT resources. In fact, backup life cycle management (BLM) is a critical part of the overall management of data.
