Operational Procedures (Additional Content)

1. Data Backup and Recovery

1.1 Backup Types: Definitions and Comparison

• Full Backup

  • Copies all selected data regardless of changes.

  • Pros: Easy and fast recovery.

  • Cons: Time-consuming and storage-heavy.

• Incremental Backup

  • Backs up only data that changed since the last backup of any kind (full or incremental).

  • Pros: Small backup size, fast execution.

  • Cons: Slower restore process (requires full + all incrementals).

• Differential Backup

  • Backs up all changes since the last full backup.

  • Pros: Faster to restore than incremental, but larger files.

  • Cons: Backup grows over time until next full backup.

Common Strategy:
Full backup weekly + incremental or differential daily.

1.2 Backup Methods: Hot, Cold, and Image-based

• Hot Backup

  • Performed while systems are online and running.

  • Useful for high-availability systems like databases.

• Cold Backup

  • Performed when systems are shut down.

  • Ensures consistency but causes downtime.

• Image-Based Backup

  • Creates a snapshot of an entire system or drive, including OS, applications, and settings.

  • Allows full system restoration onto the same or different hardware.

1.3 File-Level vs System-Level Recovery

• File-Level Recovery

  • Restores specific files or folders.

  • Ideal for accidental deletions or minor data loss.
