- tristate "NILFS2 file system support (EXPERIMENTAL)"
- depends on BLOCK && EXPERIMENTAL
- select CRC32
- 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.
