System Recovery

System recovery encompasses the methods, tools, and procedures used to restore a computing system to normal operation after experiencing failures, crashes, or data corruption. This critical aspect of system administration serves as a safety net for maintaining business continuity and data integrity.

Core Components

Backup Systems

• Data backup mechanisms
• Incremental backup vs full backup strategies
• Cloud storage integration
• Redundancy protocols

Recovery Methods

1. System Restore Points

   • Automated snapshots
   • Configuration preservation
   • Operating system state management

2. Disaster Recovery Plans

   • Business continuity procedures
   • Recovery time objectives (RTOs)
   • Risk management considerations

Common Recovery Scenarios

Hardware Failures

• Drive failures
• RAID recovery
• Component replacement procedures
• Hardware diagnostics

Software Issues

• Operating system corruption
• Malware removal
• Registry repair
• Application reinstallation

Best Practices

1. Regular Testing
