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.
