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. | ||
