11

DESCRIPTION

13       This VFS module is part of the samba(7) suite.
14
15       The vfs_shadow_copy VFS module functionality that is similar to
16       Microsoft Shadow Copy services. When setup properly, this module allows
17       Microsoft Shadow Copy clients to browse "shadow copies" on Samba
18       shares.
19
20       This module is stackable.
21

CONFIGURATION

23       vfs_shadow_copy relies on a filesystem snapshot implementation. Many
24       common filesystems have native support for this.
25
26       Filesystem snapshots must be mounted on specially named directories in
27       order to be recognized by vfs_shadow_copy. The snapshot mount points
28       must be immediate children of a the directory being shared.
29
30       The snapshot naming convention is @GMT-YYYY.MM.DD-hh.mm.ss, where:
31
32       ·   YYYY is the 4 digit year
33
34       ·   MM is the 2 digit month
35
36       ·   DD is the 2 digit day
37
38       ·   hh is the 2 digit hour
39
40       ·   mm is the 2 digit minute
41
42       ·   ss is the 2 digit second.
43
44
45       The vfs_shadow_copy snapshot naming convention can be produced with the
46       following date(1) command:
47
48                TZ=GMT date +@GMT-%Y.%m.%d-%H.%M.%S
49
50

EXAMPLES

52       Add shadow copy support to user home directories:
53
54                   [homes]
55                vfs objects = shadow_copy
56

CAVEATS

58       This is not a backup, archival, or version control solution.
59
60       With Samba or Windows servers, vfs_shadow_copy is designed to be an
61       end-user tool only. It does not replace or enhance your backup and
62       archival solutions and should in no way be considered as such.
63       Additionally, if you need version control, implement a version control
64       system.
