ZFS Filesystem for FUSE/Linux progressing

About

ZFS is an advanced modern filesystem from Sun Microsystems, originally designed for Solaris/OpenSolaris.

This project is a port of ZFS to the FUSE framework for the Linux operating system.

It is being sponsored by Google, as part of the Google Summer of Code 2006 program.

Features

ZFS has many features which can benefit all kinds of users - from the simple end-user to the biggest enterprise systems. ZFS list of features:

    *

      Provable integrity - it checksums all data (and meta-data), which makes it possible to detect hardware errors (hard disk corruption, flaky IDE cables..). Read how ZFS helped to detect a faulty power supply after only two hours of usage, which was previously silently corrupting data for almost a year!
    *

      Atomic updates - means that the on-disk state is consistent at all times, there's no need to perform a lengthy filesystem check after forced reboots/power failures.
    *

      Instantaneous snapshots and clones - it makes it possible to have hourly, daily and weekly backups efficiently, as well as experiment with new system configurations without any risks.
    *

      Built-in (optional) compression
    *

      Highly scalable
    *

      Pooled storage model - creating filesystems is as easy as creating a new directory. You can efficiently have thousands of filesystems, each with it's own quotas and reservations, and different properties (compression algorithm, checksum algorithm, etc..).
    *

      Built-in stripes (RAID-0), mirrors (RAID-1) and RAID-Z (it's like software RAID-5, but more efficient due to ZFS's copy-on-write transactional model).
    *

      Among others (variable sector sizes, adaptive endianness, ...)
