Explanation
The archive bit (also called the modified bit) is a file attribute that Windows sets whenever a file is created or modified. An incremental backup backs up only files that have changed since the last backup of any type, and then it clears (resets) the archive bit on each file it backs up. This marks those files as 'already backed up,' so the next incremental backup only captures newly changed files. A differential backup (A) also backs up changed files but does NOT reset the archive bit - it keeps accumulating all changes since the last full backup. A snapshot (B) captures a point-in-time image of a volume and does not interact with the archive bit in the same way. A synthetic full (D) reconstructs a full backup from existing backup sets and is a method, not an archive-bit-based operation.
