195 NILFS2 is a log-structured file system (LFS) supporting continuous
196 snapshotting. In addition to versioning capability of the entire
197 file system, users can even restore files mistakenly overwritten or
198 destroyed just a few seconds ago. Since this file system can keep
199 consistency like conventional LFS, it achieves quick recovery after
200 system crashes.
201
202 NILFS2 creates a number of checkpoints every few seconds or per
203 synchronous write basis (unless there is no change). Users can
204 select significant versions among continuously created checkpoints,
205 and can change them into snapshots which will be preserved for long
206 periods until they are changed back to checkpoints. Each
207 snapshot is mountable as a read-only file system concurrently with
208 its writable mount, and this feature is convenient for online backup.
209
210 Some features including atime, extended attributes, and POSIX ACLs,
211 are not supported yet.
212
213 To compile this file system support as a module, choose M here: the
214 module will be called nilfs2. If unsure, say N.
