vfs_shell_snap(8) 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:

m[blue]shell_snap:check path commandm[]

• 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.

m[blue]shell_snap:create commandm[]

• 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.

m[blue]shell_snap:delete commandm[]

• 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.

CONFIGURATION

                [share]
                m[blue]vfs objects = shell_snapm[]
                m[blue]shell_snap:check path command = snap_check_path.shm[]
                m[blue]shell_snap:create command = snap_create.shm[]
                m[blue]shell_snap:delete command = snap_delete.shm[]

Samba's FSRVP server must be configured in the [global] section: 

                [global]
                m[blue]rpc_daemon:fssd = forkm[]
                m[blue]registry shares = yesm[]
                m[blue]include = registrym[]
