NAME
       vfs_streams_xattr - Store alternate data streams in posix xattrs

SYNOPSIS
       vfs objects = streams_xattr

DESCRIPTION
       This VFS module is part of the samba(7) suite.

       The vfs_streams_xattr enables storing of NTFS alternate data streams in
       the file system. As a normal posix file system does not support the
       concept of multiple data streams per file, the streams_xattr module
       stores the data in posix extended attributes (xattrs). The name of
       these attributes by default is user.DosStream."ADS-NAME". The prefix
       "user.DosStream." can be changed with the module option
       streams_xattr:prefix, but be aware that this will also expose those ADS
       over the SMB extended attributes interface.

       The file system that is shared with this module enabled must support
       xattrs.

       Please note that most file systems have severe limitations on the size
       of xattrs. So this module might work for applications like IE that
       stores small zone information in streams but will fail for applications
       that store serious amounts of data in ADSs.

OPTIONS
       streams_xattr:prefix = STRING
           Name prefix used when storing an ADS in an xattr, defaults to
           user.DosStream.. Changing this will also expose ADS over the SMB
           extended attributes interface.

       streams_xattr:store_stream_type = [yes|no]
           Whether the xattr names for Alternate Data Streams of type "$DATA"
           are suffixed by the stream type string ":$DATA". The default is
           yes.

EXAMPLES
                   [share]
                vfs objects = streams_xattr
