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 Linux kernel.

This site provides information and resources related to the NILFS filesystem.
