Lemezképfelvétele

Lemezképfelvétele refers to the process of creating a disk image, which is essentially a complete copy of the data on a storage medium like a hard drive, SSD, USB drive, or CD/DVD. This process captures the entire structure of the disk, including the file system, boot sectors, and all individual files and folders, at a specific point in time.

The primary purpose of lemezképfelvétele is for backup and disaster recovery. By creating an image, users can restore their system to a previous working state in case of hardware failure, software corruption, or accidental data deletion. It is also commonly used for forensic analysis, allowing investigators to examine a digital medium without altering the original data. Software cloning tools are frequently employed for this task, offering options to create full, incremental, or differential images. Full images capture everything, while incremental images only save changes since the last backup, and differential images save changes since the last full backup.

The resulting disk image is typically stored as a single file on another storage device. This file can then be used to restore the original disk or to create an exact replica on a new drive. Understanding and utilizing lemezképfelvétele is a fundamental practice in data management and digital security.
