Sun confirms Apple will add ZFS on Mac OS X Leopard
More than a year ago, there was a rumor that Mac OS X Leopard will use the next-generation ZFS file system.
Now this rumor can be called officially confirmed. As MacRumors.com notes, yesterday Jonathan Schwartz, president of Sun Microsystems, said that instead of HFS +, the new file system in Leopard will be ZFS .
The ZFS file system (Zettabyte File System) was originally developed in the walls of Sun for the Solaris operating system. ZFS protects all files with a 64-bit checksum to detect and correct data integrity problems. And, like the 128-bit file system, ZFS can handle larger volumes than existing versions of Windows, OS X, and Linux.
One of the biggest changes ZFS gives us is the so-called virtual storage pool model , called zpool. A pool is built from virtual devices (vdevs), each of which is either a physical device or a mirror (RAID 1) of one or more devices, or (RAID Z) - a group of two or more devices. The capacity of all virtual devices is then available for all file systems in zpool.

ZFS also allows you to take "snapshots" (fingerprints) of the state of the file system at any point in time, using RAID to automatically back up data and offering the possibility of compression.
