NAME

7       deletion

SYNOPSIS

10       vfs objects = shell_snap
11

DESCRIPTION

13       This VFS module is part of the samba(8) suite.
14
15       The vfs_shell_snap VFS provides shell-script callouts for snapshot
16       creation and deletion operations issued by remote clients using the
17       File Server Remote VSS Protocol (FSRVP).
18
19       The following shell callouts may be configured in smb.conf:
20
21       shell_snap:check path command
22
23              •   Called when an FSRVP client wishes to check whether a given
24                  share supports snapshot create/delete requests.
25
26              •   The command is called with a single share_path argument.
27
28              •   The command must return 0 if share_path is capable of being
29                  snapshotted.
30
31
32       shell_snap:create command
33
34              •   Called when an FSRVP client wishes to create a snapshot.
35
36              •   The command is called with a single share_path argument.
37
38              •   The command must return 0 status if the snapshot was
39                  successfully taken.
40
41              •   The command must output the path of the newly created
42                  snapshot to stdout.
43
44
45       shell_snap:delete command
46
47              •   Called when an FSRVP client wishes to delete a snapshot.
48
49              •   The command is called with base_share_path and
50                  snapshot_share_path arguments.
51
52              •   The command must return 0 status if the snapshot was
53                  successfully removed.
54
55       All commands are executed as the authenticated FSRVP client user.
56
57       This module is stackable.
