- 3. INTRODUCTION TO BACK UP β’ Backup is the process of creating copies of data to safeguard against loss or corruption. These copies can be used to restore original data after an event like hardware failure, data corruption, accidental deletion, or a cyber-attack. β’ Purpose: Backup ensures that data can be recovered quickly, minimizing downtime and loss of critical information. β’ Real-World Example: Companies typically keep backup copies of all sensitive data, such as customer databases, financial records, and critical software applications.
- 4. IMPORTANCES OF BACKUP β’ Protection against Data Corruption: Backups can help recover data corrupted due to software glitches, hardware malfunction, or malicious activities. β’ Hardware Failure: Even with the most advanced hardware, thereβs always a chance of failure. Backup ensures that a malfunctioning hard drive doesnβt mean complete data loss. β’ Security against Ransomware/Cyber-Attacks: With the rise of ransomware, backups provide a safety net to restore data without paying a ransom.
- 5. CONT⦠⒠Human Error: Accidental deletions or overwriting files are common, and backups help recover such losses. ⒠Compliance with Regulations: In industries like healthcare, finance, and education, regulations such as GDPR, HIPAA, or PCI-DSS mandate secure and frequent data backups to ensure privacy and availability of critical data.
- 6. TYPES OF BACK 1. Full Backup: A full backup captures all files and data, regardless of any changes made since the last backup. β’ Pros: Complete data recovery in one step. β’ Cons: It takes longer to create and consumes significant storage space. β’ Example: A business may perform a full backup of all its servers once a week to ensure all data is up to date.
- 7. 2. Incremental Backup: Only backs up the data that has changed since the last backup (whether it was a full or incremental backup). β’ Pros: Faster backup process and reduced storage needs. β’ Cons: Recovery can be complex, as it requires restoring the last full backup plus each incremental backup in sequence. β’ Example: A daily incremental backup system only copies files altered within the day, reducing storage usage.
- 8. 3.Differential Backup: Backs up all the data that has changed since the last full backup. β’ Pros: Faster than full backup and easier to restore than incremental, as only the last full and last differential backups are needed. β’ Cons: Takes more time and space than incremental backups. β’ Example: If a full backup is taken every Sunday, then a differential backup taken on Thursday will capture all changes since Sunday.
- 9. BACKUP METHODS On-Site Backup: Backups are stored locally on physical drives or servers within the same location as the primary data. β’ Advantages: Fast recovery times due to local access, more control over the storage process. β’ Disadvantages: Prone to local disasters such as fires, floods, or theft. β’ Use Case: Small businesses might store backups on external hard drives or network-attached storage (NAS) devices.
- 10. Off-Site Backup: Backup data is transferred to a different physical location (e.g., another office or storage facility). β’ Advantages: Data is protected from local disasters (fire, flood, etc.). β’ Disadvantages: Higher costs, slower recovery times compared to on-site storage. β’ Use Case: Enterprises often replicate data to secondary data centers in other cities or countries.
- 11. Cloud Backup Backup data is stored on remote cloud servers managed by third-party providers. β’ Advantages: Easy access from anywhere, scalable storage, automated backups, and typically more secure. β’ Disadvantages: Dependent on internet access for backup and recovery; potential privacy/security concerns. β’ Use Case: A growing number of businesses rely on cloud services like Amazon Web Services (AWS), Microsoft Azure, or Google Cloud for automatic, off-site backups.
- 12. BACKUP STRATEGIES 3-2-1 Backup Rule: β’ Keep 3 copies of your data: 1 original and 2 backups. β’ Store 2 backups on different types of media (e.g., external hard drive, cloud). β’ Keep 1 copy offsite for disaster recovery purposes. β’ Rationale: This ensures redundancy while mitigating the risk of both copies being lost simultaneously due to a single event.
- 13. BACKUP FREQUENCY Varies depending on data volatility: β’ High-volatility data (e.g., databases) might need daily or hourly backups. β’ Low-volatility data (e.g., archived documents) may require weekly or monthly backups. β’ Automated vs. Manual Backups: β’ Automated Backups: Most modern backup systems allow scheduling of regular backups without human intervention, ensuring consistency. β’ Manual Backups: May be needed for custom backups or irregular tasks, but these are prone to human error and oversight.
- 14. CAHLLENGES WITH BACKUP β’ Managing large volumes of data: As data grows exponentially, storing and managing backups becomes more complex. β’ Ensuring backup consistency: Verifying that all data is backed up correctly without corruption or loss. β’ Testing backups for reliability: Regular testing is critical to ensure that backups are usable and can be restored when needed. β’ Backup Security: Backups need to be protected from unauthorized access (encryption, access control, etc.) to avoid data breaches.
- 15.
