  184 + help
  185 + NILFS2 is a log-structured file system (LFS) supporting continuous
  186 + snapshotting. In addition to versioning capability of the entire
  187 + file system, users can even restore files mistakenly overwritten or
  188 + destroyed just a few seconds ago. Since this file system can keep
  189 + consistency like conventional LFS, it achieves quick recovery after
  190 + system crashes.
  191 +
  192 + NILFS2 creates a number of checkpoints every few seconds or per
  193 + synchronous write basis (unless there is no change). Users can
  194 + select significant versions among continuously created checkpoints,
  195 + and can change them into snapshots which will be preserved for long
  196 + periods until they are changed back to checkpoints. Each
  197 + snapshot is mountable as a read-only file system concurrently with
  198 + its writable mount, and this feature is convenient for online backup.
  199 +
  200 + Some features including atime, extended attributes, and POSIX ACLs,
  201 + are not supported yet.
  202 +
  203 + To compile this file system support as a module, choose M here: the
  204 + module will be called nilfs2. If unsure, say N.
