Data Backup

- A) To encrypt data for security
- B) To recover data in case of loss or corruption
- C) To move data to a different location
- D) To share data with other users

- Which type of backup involves copying all selected data, regardless of whether it has changed since the last backup?
- A) Incremental backup
- B) Differential backup
- C) Full backup
- D) Synthetic backup
- Answer: C) Full backup
Important Note:
| Feature | Full Backup | Incremental Backup | Differential Backup |
| Definition | Copies all data | Copies only data changed since the last backup (full or incremental) | Copies all data changed since the last full backup |
| Backup Speed | Slow | Fast | Moderate |
| Storage Usage | High (each backup is a complete copy) | Low (only changed data is copied) | Moderate (only changes since the last full backup are copied) |
| Restoration Speed | Fast (single backup needed) | Slow (requires last full backup and all incremental backups since then) | Moderate (requires last full backup and the most recent differential backup) |
| Complexity | Simple | Complex (requires tracking changes since last backup) | Moderate (requires tracking changes since last full backup) |
| Advantages | Easy to manage and restore | Efficient storage and fast backups | Faster restoration than incremental backups while still saving space compared to full backups |
| Disadvantages | High storage and time-consuming backups | Slower restoration, complex management | Requires more storage than incremental backups and can still be time-consuming for large changes |
