NAME
vfs_shell_snap - Shell script callouts for snapshot creation and
deletion
SYNOPSIS
vfs objects = shell_snap
DESCRIPTION
This VFS module is part of the samba(8) suite.
The vfs_shell_snap VFS provides shell-script callouts for snapshot
creation and deletion operations issued by remote clients using the
File Server Remote VSS Protocol (FSRVP).
The following shell callouts may be configured in smb.conf:
shell_snap:check path command
· Called when an FSRVP client wishes to check whether a given share
supports snapshot create/delete requests.
· The command is called with a single share_path argument.
· The command must return 0 if share_path is capable of being
snapshotted.
shell_snap:create command
· Called when an FSRVP client wishes to create a snapshot.
· The command is called with a single share_path argument.
· The command must return 0 status if the snapshot was successfully
taken.
· The command must output the path of the newly created snapshot to
stdout.
shell_snap:delete command
· Called when an FSRVP client wishes to delete a snapshot.
· The command is called with base_share_path and snapshot_share_path
arguments.
· The command must return 0 status if the snapshot was successfully
removed.
All commands are executed as the authenticated FSRVP client user.
This module is stackable.
