Chapter 10 Backup and Recovery

Understanding AS/400 System Operations Introduction To backup is to copy some or all of a computer’s software to a storage location independent of the computer.   Understanding AS/400 System Operations

Understanding AS/400 System Operations Introduction To restore is to copy that remotely stored data back onto the computer and be able to use it. Understanding AS/400 System Operations

Understanding AS/400 System Operations Reasons to Backup Object failure: Most common reason. Objects deleted or damaged or corrupted. System failure: Less common. Power lost or disk units fail etc. Understanding AS/400 System Operations

Understanding AS/400 System Operations Reasons to Backup Site movement: Company moves from one computer to another. Common for disaster recovery. Efficiently save infrequently used information: Large objects take up disk space infrequently used. Site loss. Extremely rare. Flood, fire, riots, etc Understanding AS/400 System Operations

Understanding AS/400 System Operations Copy Vs. Save Copy command: Two copies of the file. Accessed at any time. Could be lost if disk problem. Save command: Data files cannot be accessed except by restore. Object header updated. Off-site security. Understanding AS/400 System Operations
