Backup and Recovery

2. 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

3. 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

4. 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

5. 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

6. 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.
