What is the difference between image-based backup and file-level backup?

• A. Image-based backup captures an entire disk/partition including OS and apps for bare-metal restores; file-level backup backs up individual files/folders.
• B. Image-based backup backs up only system files; file-level backup backs up everything except OS
• C. Image-based backup backs up emails only.
• D. There is no difference between image-based and file-level backups.

Answer: (A)

Image-based backups capture the entire disk or a full partition, including the operating system, installed applications, settings, and all data. This makes it possible to restore the entire system to a working state quickly, even onto different hardware if the tool supports it—essentially a full, bootable copy of the system. File-level backups, by contrast, save only the individual files and folders you select, which is great for protecting user data but won’t reproduce a working OS or installed programs on its own. So the first approach covers the whole system for a bare-metal restore, while the second focuses on specific files.
