Recovery Principles Recovery is a Complex Art: Plan for it, Test in Advance Know Your Operating Requirements How much data can you afford to lose? How long can your applications be offline for backup or recovery? How quickly can you recover? Are the capabilities to reverse changes needed? What resources are available for recovery? Can your recovery system reliably respond in the time required? Requires high data integrity, rapid access and performance Source: Strategic Research Corp
