VFS_SHADOW_COPY(1M) System Administration tools VFS_SHADOW_COPY(1M)NAMEvfs_shadow_copy - Make a Samba share read only for a specified time
period
SYNOPSIS
vfs objects = shadow_copy
DESCRIPTION
This VFS module is part of the samba(7) suite.
The vfs_shadow_copy 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 module is stackable.
CONFIGURATIONvfs_shadow_copy 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_copy. 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_copy snapshot naming convention can be produced with the
following date(1) command:
TZ=GMT date +@GMT-%Y.%m.%d-%H.%M.%S
EXAMPLES
Add shadow copy support to user home directories:
[homes]
vfs objects = shadow_copy
CAVEATS
This is not a backup, archival, or version control solution.
With Samba or Windows servers, vfs_shadow_copy 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 3.0.25 of the Samba suite.
AUTHOR
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.

NOTES
Source code for Samba is available in the SUNWsmbaS package.
Samba(7) delivers the set of four SMF(5) services as can be seen from
the following example:
$ svcs samba wins winbind swat
STATE STIME FMRI
disabled Apr_21 svc:/network/samba:default
disabled Apr_21 svc:/network/winbind:default
disabled Apr_21 svc:/network/wins:default
disabled Apr_21 svc:/network/swat:default
where the services are:
"samba"
runs the smbd daemon managing the CIFS sessions
"wins"
runs the nmbd daemon enabling the browsing (WINS)
"winbind"
runs the winbindd daemon making the domain idmap
"swat"
Samba Web Administration Tool is a service providing access to
browser-based Samba administration interface and on-line
documentation. The service runs on software loopback network
interface on port 901/tcp, i.e. opening "http://localhost:901/" in
browser will access the SWAT service on local machine.
Please note: SWAT uses HTTP Basic Authentication scheme where user name
and passwords are sent over the network in clear text. In the SWAT case
the user name is root. Transferring such sensitive data is advisable
only on the software loopback network interface or over secure
networks.
