The Log-Structured file system prevents data write operations from overwriting the disk blocks.  So, it minimizes a damage of file data and file system consistency on hardware failure. The Log-Structured system is able to create a snapshot of the file system immediately and to check the file system speedy.  The ``nilfs'' implements file and inode block management by B-Tree structure. The B-Tree structure enables the ``nilfs'' to create a huge file, to store a large number of files.
