<title>DESCRIPTION</title>
<para>This VFS module is part of the
<citerefentry><refentrytitle>samba</refentrytitle>
<manvolnum>8</manvolnum></citerefentry> suite.</para>
<para>
The <command>vfs_btrfs</command> VFS module exposes Btrfs
specific features for use by Samba.
</para>
<para>
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.
</para>
<para>
This module is stackable.
