vfs_shell_snap Shell script callouts for snapshot creation and deletion
`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:

- 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.

- 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.

- 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.
