Name

vfs_shadow_copy2 — Expose snapshots to Windows clients as shadow copies.

Synopsis

vfs objects = shadow_copy2

DESCRIPTION

This VFS module is part of the + samba(7) suite.

The vfs_shadow_copy2 VFS module functionality + that is similar to Microsoft Shadow Copy services. When setup properly, + this module allows Microsoft Shadow Copy clients to browse + "shadow copies" on Samba shares. +

This is a 2nd implementation of a shadow copy module. This + version has the following features:

  1. You don't need to populate your shares with symlinks to the + snapshots. This can be very important when you have thousands of + shares, or use [homes].

  2. The inode number of the files is altered so it is different + from the original. This allows the 'restore' button to work + without a sharing violation.

This module is stackable.

CONFIGURATION

vfs_shadow_copy2 relies on a filesystem + snapshot implementation. Many common filesystems have native + support for this. +

Filesystem snapshots must be mounted on + specially named directories in order to be recognized by + vfs_shadow_copy2. The snapshot mount points must + be immediate children of a the directory being shared.

The snapshot naming convention is @GMT-YYYY.MM.DD-hh.mm.ss, + where: +

  • YYYY is the 4 digit year

  • MM is the 2 digit month

  • DD is the 2 digit day

  • hh is the 2 digit hour

  • mm is the 2 digit minute

  • ss is the 2 digit second.

+

The vfs_shadow_copy2 snapshot naming convention can be + produced with the following date(1) command: + 

+	TZ=GMT date +@GMT-%Y.%m.%d-%H.%M.%S
+

OPTIONS

shadow:snapdir = SNAPDIR +

Path to the directory where snapshots are kept. +

shadow:basedir = BASEDIR +

Path to the base directory that snapshots are from. +

shadow:fixinodes = yes/no +

If you enable shadow:fixinodes + then this module will modify the apparent inode + number of files in the snapshot directories using a hash of the + files path. This is needed for snapshot systems where the + snapshots have the same device:inode number as the original + files (such as happens with GPFS snapshots). If you don't set + this option then the 'restore' button in the shadow copy UI + will fail with a sharing violation. +

EXAMPLES

Add shadow copy support to user home directories:

+        [homes]
+	vfs objects = shadow_copy2
+	shadow:snapdir = /data/snaphots
+	shadow:basedir = /data/home
+

CAVEATS

This is not a backup, archival, or version control solution. +

With Samba or Windows servers, + vfs_shadow_copy2 is designed to be an end-user + tool only. It does not replace or enhance your backup and + archival solutions and should in no way be considered as + such. Additionally, if you need version control, implement a + version control system.

VERSION

This man page is correct for version 3.2.7 of the Samba suite. +

The original Samba software and related utilities + were created by Andrew Tridgell. Samba is now developed + by the Samba Team as an Open Source project similar + to the way the Linux kernel is developed.
