A disk image typically represents a replicated version of optical media, though it can also originate from a USB flash drive. Faronics, a provider of software solutions for multi-user computing environments, highlights several benefits associated with disk images, including:

  • Streamlining the process of deploying identical systems across multiple computers, eliminating the need for individual setup or fresh OS installations on each device.
  • Facilitating incremental backups by allowing users to create numerous image variations.
  • Storing images as files enables you to preserve Mac data without retaining the physical hardware. Generate an image of the drive and archive it for future use.

A disk image is a compressed replica of a disk or folder's contents, known as a dmg file, which is identifiable by the .dmg extension in its name.
