ZFS is an advanced, next generation file system.

• It combines the features of a filesystem and a volume manager in one place.
• It is a 128-bit file system so it provides astronomically large limits to FileSystem size (256 quadrillion Zettabytes) and individual file size (16 exbibytes).

It provides:

• RAID.
• Snapshots.
• Integrity checking, including protection against bit rot.
• Automatic repair.
• Lots more…
