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