Filsystembild

Filsystembild is a German term that translates to "filesystem image" in English. It refers to a complete snapshot or copy of a file system at a specific point in time. This image captures all the data, metadata, and directory structure of the original file system.

Filesystem images are typically created for backup, disaster recovery, or forensic analysis purposes. When a filesystem image is created, it essentially duplicates the entire organization of files and folders, including their contents and attributes like permissions, timestamps, and ownership. This allows for the restoration of a system to its exact state at the time the image was taken.

The process of creating a filesystem image involves reading all sectors of the storage device that contains the file system and writing this data into a single file or a set of files. This resulting image file can then be stored separately, often on different media, to ensure its safety.

Various tools and software are available for creating and managing filesystem images. These tools can range from simple disk imaging utilities to more sophisticated forensic tools designed to extract and preserve evidence from storage media. The use of filesystem images is crucial for data integrity and provides a reliable method for data recovery in case of hardware failure, accidental deletion, or malicious attacks.
