Understanding Metal Backup: Bare Metal Image vs. File Level

4 Min Read

In the realm of data backup and recovery, understanding the difference between bare metal image and file level backups is crucial for businesses and individuals alike. Each approach has its own merits and drawbacks, and choosing the right one depends on your specific needs and circumstances.

Bare Metal Image Backup:

A bare metal image backup is a comprehensive backup of an entire system, including the operating system, applications, settings, and user data. This backup is taken at the disk level, creating an exact replica of the system’s state.

The primary advantage of this approach is that it allows for fast disaster recovery, as the entire system can be restored in one process, avoiding the need for time-consuming OS and application installs, configuration processes, and driver rollouts. Additionally, all settings are restored to new hardware with all user data intact, ensuring a smooth transition to new hardware.

File Level Backup:

A file level backup, on the other hand, only backs up individual files rather than the entire system image. This approach allows for more granular control over what is backed up, as users can decide which files are important and only back up those files. The primary advantage of this approach is that it requires less storage space, as only important data files are backed up, rather than the entire system. However, the downside is that it can take longer to recover from a disaster, as each component must be reinstalled and configured individually.


When comparing bare metal image and file level backups, there are several factors to consider. Protection against total hardware failure is better with bare metal backup, as they allow for the entire system to be restored in its pre-crash state. However, file level backups offer better protection against partial hardware failure, as only the affected files need to be restored.

Both approaches offer protection against viruses and malware, although bare metal backups may be more effective due to their comprehensive nature. Data verification and testing are easier with file level backups, as individual files can be verified and tested separately.

Accessibility of backed up data is generally better with file level backups, as they allow for easier access to individual files through a web browser. Finally, storage requirements are higher with bare metal backups, as they require sufficient space to store the entire system image.


Choosing the right backup approach depends on your specific needs and circumstances. For businesses and individuals who require fast disaster recovery and cannot afford lengthy downtime, bare metal image backups are the best choice.

However, for those who prioritize granular control over what is backed up and lower storage requirements, file level backups may be the better option. Ultimately, the key is to understand the strengths and weaknesses of each approach and choose the one that best fits your needs.
