Document Summary
Data recovery is the process in which highly trained engineers evaluate and extract data from damaged media and return it in an intact format. Many people, even computer experts, fail to recognize data recovery as an option during a data crisis. But it is possible to retrieve files that have been deleted and passwords that have been forgotten or to recover entire hard drives that have been physically damaged: data back-up and recovery ***** Back-up window: the back-up window is the period of time when back-ups can be run. The back-up window is generally timed to occur during nonproduction periods when network bandwidth and.
