BTRFS is a file system based on the copy-on-write (COW) principle, initially designed at Oracle Corporation for use in Linux. The development of Btrfs began in 2007, and since August 2014 the file system's on-disk format has been marked as stable.

In 2015, Btrfs was adopted as the default filesystem for SUSE Linux Enterprise Server 12. SUSE reaffirmed its commitment to Btrfs in 2017 after RedHat announced to stop supporting Btrfs.

Btrfs is intended to address the lack of pooling, snapshots, checksums, and integral multi-device spanning in Linux file systems.

It is easy to set up and use BTRFS. In this simple introduction, we're going to set up BTRFS under Funtoo Linux using an existing debian-sources or debian-sources-lts kernel, like the one that comes pre-built for you with Funtoo Linux, and we will also be using our BTRFS storage pool for storing data that isn't part of the Funtoo Linux installation itself. Funtoo Linux will boot from a non-BTRFS filesystem, and as part of the initialization process will initialize our BTRFS storage pool and mount it at the location of our choice.
