| 194 | help |
| 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. |
