File system virtualization primarily deals with which aspect of data handling?

File system virtualization is a technology that abstracts the physical file system to create a virtual environment for managing files and data. This approach allows applications to interact with data without needing to know the underlying physical storage locations. Therefore, it primarily focuses on virtualizing data at the file system level, enabling functionalities such as improved data management, enhanced backup solutions, and efficient data access.

By leveraging file system virtualization, organizations can optimize storage utilization and streamline data handling processes. This technology also allows for easier data recovery and migration, as the virtual file system can be manipulated independently of the physical storage medium. In essence, file system virtualization enhances how data is managed and can improve IT infrastructure flexibility and efficiency.
