| human error | Accidentally deleting system files or work data |
| natural disaster | Fire/flood damaged storage equipment |
2. Comparison of mainstream backup methods
Depending on the storage medium and operation method, backups can be divided into the following types:
| Backup method | Advantages | Disadvantages | Applicable scenarios |
| External hard drive backup | Fast speed and large capacity | Requires manual operation | Regular backup of large-capacity data |
| Cloud storage backup | Automatic synchronization, remote security | Ongoing charges | Real-time backup of important files |
| Network Attached Storage (NAS) | Sharing across multiple devices | High initial cost | Enterprise/home multi-terminal |
| System image backup | Full system recovery | Takes up a lot of space | System crash emergency |
