Description

NAME
       vfs_shadow_copy - Expose snapshots to Windows clients as shadow copies.

SYNOPSIS
       vfs objects = shadow_copy

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

       The vfs_shadow_copy VFS module functionality that is similar to
       Microsoft Shadow Copy services. When setup properly, this module allows
       Microsoft Shadow Copy clients to browse "shadow copies" on Samba
       shares.

       This module is stackable.

CONFIGURATION
       vfs_shadow_copy relies on a filesystem snapshot implementation. Many
       common filesystems have native support for this.

       Filesystem snapshots must be mounted on specially named directories in
       order to be recognized by vfs_shadow_copy. The snapshot mount points
       must be immediate children of a the directory being shared.

       The snapshot naming convention is @GMT-YYYY.MM.DD-hh.mm.ss, where:

              o   YYYY is the 4 digit year

              o   MM is the 2 digit month

              o   DD is the 2 digit day

              o   hh is the 2 digit hour

              o   mm is the 2 digit minute

              o   ss is the 2 digit second.


       The vfs_shadow_copy snapshot naming convention can be produced with the
       following date(1) command:

                TZ=GMT date +@GMT-%Y.%m.%d-%H.%M.%S


EXAMPLES
       Add shadow copy support to user home directories:

                   [homes]
                vfs objects = shadow_copy

CAVEATS
       This is not a backup, archival, or version control solution.

       With Samba or Windows servers, vfs_shadow_copy is designed to be an
       end-user tool only. It does not replace or enhance your backup and
       archival solutions and should in no way be considered as such.
       Additionally, if you need version control, implement a version control
       system.

VERSION
       This man page is part of version 4.9.3 of the Samba suite.
