NAME
       vfs_btrfs - Utilize features provided by the Btrfs filesystem

SYNOPSIS
       vfs objects = btrfs

DESCRIPTION
       This VFS module is part of the samba(8) suite.

       The vfs_btrfs VFS module exposes Btrfs specific features for use by Samba.

       Btrfs allows for multiple files to share the same on-disk data through the use cloned ranges. When an SMB client issues a request to copy
       duplicate data (via FSCTL_SRV_COPYCHUNK), this module maps the request to a Btrfs clone range IOCTL, instead of performing reads and writes
       required by a traditional copy. Doing so saves storage capacity and greatly reduces disk IO.

       This module is stackable.

CONFIGURATION
       vfs_btrfs requires that the underlying share path is a Btrfs filesystem.

		     [share]
		     vfs objects = btrfs

VERSION
       This man page is correct for version 4.1.0 of the Samba suite.

AUTHOR
       The original Samba software and related utilities were created by Andrew Tridgell. Samba is now developed by the Samba Team as an Open
       Source project similar to the way the Linux kernel is developed.
