Imate backup4/9/2023 ![]() ![]() This backup is considered crash-consistent since all data is taken at exactly the same point in time relying on Microsoft’s Volume Shadow Copy (VSS) operating at the volume level (for Windows-based operating systems). The entire backup is saved as one file known as an image. Image-based backup is the process of backing up an entire virtual machine or physical machine along with the operating system, configuration files and system state. Let’s take a closer look at image-based backups. When it comes to the backup of operating systems and virtual machines, image-based backup is the better and more reliable option. Thus, even if all of the files from a source VM are copied, the backup will not be crash-consistent, complicating the recovery process later. However, while you are copying the content of one file, another one might be changed. Note: Technically, it is possible to back up the operating system using the file-based backup method because the configuration of the OS is stored in files. Operating systems contain many running operations, like data stored in RAM or input and output operations. An operating system, whether installed on a physical machine or on a virtual machine, is more complex than just a set of files. When you need to back up a complete system, such as a whole OS or a virtual machine, a file-based backup is not enough. However, to perform file-based backups, you usually need a piece of software called an agent on the source computer and another copy of the agent on the target host (whether it is a home PC or a server in the cloud). File-based backups work well when you generate and store a relatively small amount of data, especially if this data is platform-independent. This backup approach operates at the file-system level to process source files. What Is File-Based Backup?įile-based backups are copies of individual files and folders.

NAKIVO Backup & Replication is a comprehensive image-based data protection solution for virtual, physical, cloud and SaaS environments. This post details the similarities and differences between the two methods. Although some may think that the two methods can be used interchangeably, a good understanding of each can help strengthen an organization’s data protection strategy. Image-based and file-based backups are used to achieve different goals. It provides comprehensive data protection for the entire operating system, including files and other application data, and simplifies recoveries. Image-based backup is a modern backup approach designed for today’s business IT infrastructures. However, they are not the optimal choice since these types of solutions cannot ensure data recovery in case of data loss or corruption. When it comes to backing up separate files, many organizations rely on file-based backups and file sync solutions such as Dropbox, Google Drive and OneDrive. In today’s data protection landscape, there are numerous backup types that you can use to safeguard your data. ![]()
