What is data archiving?

Data archiving, from a database perspective, is the process of copying older, unneeded data from the database to another location (file system, another database, etc). The archived data is then removed from the database.

Data archiving is done for two main reasons. One, removing older data from the database so as to control the database growth. Two, being able to recall the removed data in the future if needed for an audit, compliance reasons, or to recover from a mistake.
