## Data Backup Methods

### Interactive Matching Exercise

Match the data backup method currently used in organizations (from the dropdown) to its description below:

1. **Description:** Backup of all selected files regardless of the state of the archive flag  
   **Dropdown Options:**
   - Choose...
   - Differential backup
   - System Image
   - Full backup
   - Incremental backup
   - Daily backup

2. **Description:** All the data on a computer is backed up, including files, applications, and the operating system  
   **Dropdown Options:**
   - Choose...
   - Differential backup
   - System Image
   - Full backup
   - Incremental backup
   - Daily backup

3. **Description:** Backs up files created or changed since the last backup of any kind  
   **Dropdown Options:**
   - Choose...
   - Differential backup
   - System Image
   - Full backup
   - Incremental backup
   - Daily backup

### Understanding Backup Types

To assist in correctly matching the backup types to their descriptions, here are brief explanations of each type:

1. **Differential Backup:**
   - Backs up all files that have changed since the last full backup.

2. **System Image:**
   - A complete copy of the system's current state, including the operating system, applications, and files.

3. **Full Backup:**
   - Backs up all data regardless of previous backups. This includes all selected files.

4. **Incremental Backup:**
   - Backs up only the data that has changed since the last full or incremental backup.

5. **Daily Backup:**
   - Typically backs up specific data every day, potentially overlapping with other types of backups depending on the organization's strategy.

Remember to choose the most appropriate backup type for your needs to ensure data integrity and recovery efficiency.
