=== Journaling file system ===
Versioning file systems should not be confused with [[journaling file system]]s. Whereas [[journaling file system]]s work by keeping a log of the changes made to a file before committing those changes to that file system (and overwriting the prior version), a versioning file system keeps previous copies of a file when saving new changes. The two features serve different purposes and are not mutually exclusive.
