Welcome to NILFS
NILFS is a log-structured file system supporting versioning of the entire file system and continuous snapshotting which allows users to even restore files mistakenly overwritten or destroyed just a few seconds ago.
NILFS was developed by NTT Laboratories and published as an open-source software under GPL license, and now available as a part of the Linux kernel.
This site provides information and source code of programs related to the NILFS filesystem.
