It is said that, in life, death and taxes are the only certain things but when it comes to IT systems, failure is guaranteed. Disaster recovery is not about IF systems fail but rather WHEN they do.
Failure arises from a variety of sources ranging from the fact that we are human(to err is human) to sources beyond our control such as natural disasters. People make mistakes; your Database Admin can accidentally drop a database table or your IT staff may forget to buy a crucial support license in order to save costs.
