A port of the ZFS file system from Sun, the most advanced file system in the world!





ZFS is the most advanced file system ever invented. The ZFS-FUSE project makes it possible to create, mount, use and manage ZFS file systems under Linux, bringing the uncontested reliability and large feature set of ZFS to the Linux world.

What ZFS offers to you

ZFS has many features for all kinds of users - from the simple end-user to the biggest enterprise systems:

* 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
* High scalability
* 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, ...)
