VFS_SNAPPER(8) System Administration tools VFS_SNAPPER(8)NAMEvfs_snapper - Expose snapshots managed by snapper as shadow-copies
SYNOPSIS
vfs objects = snapper
DESCRIPTION
This VFS module is part of the samba(8) suite.
The vfs_snapper VFS module exposes snapshots managed by snapper for use
by Samba. This provides the ability for remote SMB clients to access
shadow-copies via Windows Explorer using the "previous versions"
dialog.
Snapshots can also be created and remove remotely, using the File
Server Remote VSS Protocol (FSRVP). Snapshot creation and deletion
requests are forwarded to snapper via DBus.
This module is stackable.
CONFIGURATION
The underlying share path must have a corresponding snapper
configuration file. The snapshot directory tree must allow access for
relavent users.
[share]
vfs objects = snapper
For remote snapshot creation and deletion, Samba's FSRVP server must be
configured in the [global] section:
[global]
rpc_daemon:fssd = fork
registry shares = yes
include = registry
PERMISSIONS
Snapper stores snapshots under a .snapshots subdirectory. This
directory must permit traversal for any users wishing to access
snapshots via the Windows Explorer previous versions dialog. By
default, traversal is forbidden for all non-root users. Additionally,
users must be granted permission to list snapshots managed by snapper,
via snapper's ALLOW_USERS or ALLOW_GROUPS options. Snapper can grant
these users and groups .snapshots traversal access automatically via
the SYNC_ACL option.
Remote snapshot creation and deletion is only permitted by Samba for
Active Directory administrators, backup operators, or users explicitly
granted SeBackupPrivilege. Snapper must also permit creation and
deletion for the appropriate user, via snapper's ALLOW_USERS or
ALLOW_GROUPS options.
The DiskShadow.exe FSRVP client initially authenticates as the Active
Directory computer account. This account must therefore be granted the
same permissions as the user account issuing the snapshot creation and
deletion requests.
VERSION
This man page is correct for version 4.3.0 of the Samba suite.
