NAME
vfs_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.
CONFIGURATION
vfs_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:
o YYYY is the 4 digit year
o MM is the 2 digit month
o DD is the 2 digit day
o hh is the 2 digit hour
o mm is the 2 digit minute
o ss is the 2 digit second.
The vfs_shadow_copy snapshot naming convention can be produced with the fol-
lowing 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. Addi-
tionally, if you need version control, implement a version control sys-
tem.
VERSION
This man page is correct for version 3.0.25 of the Samba suite.
