ZFS (previously Zettabyte File System) is a file system with volume management capabilities. It began as part of the Sun Microsystems Solaris operating system in 2001. Large parts of Solaris, including ZFS, were published under an open source license as OpenSolaris for around 5 years from 2005 before being placed under a closed source license when Oracle Corporation acquired Sun in 2009–2010.
Some filesystems, such as Btrfs, [32] and ZFS/OpenZFS (with per-dataset copies=1|2|3 property), [33] support creating multiple copies of the same data on a single drive or disks pool, protecting from individual bad sectors, but not from large numbers of bad sectors or complete drive failure. This allows some of the benefits of RAID on computers ...
As the FSF (Free Software Foundation) claimed that there was a legal incompatibility between the CDDL and the GPL in 2005, Sun's implementation of the ZFS file system couldn't be used as a basis for the development of a module in the Linux kernel, couldn't be merged into the mainline Linux kernel, and Linux distributions generally did not include it as a precompiled kernel module.

zFS technology was first released in 1995 as the Local File System, a lower layer of the DCE Distributed File System. It was available on MVS/ESA V5R2.2 and all OS/390 releases. DFS/LFS was provided as a part of the DCE feature, not part of the base operating system.
