vfs_shadow_copy - Expose snapshots to Windows clients as shadow copies.

This VFS module is part of the samba
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.
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:
•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
TZ=GMT date +@GMT-%Y.%m.%d-%H.%M.%S
Add shadow copy support to user home directories:
vfs objects = shadow_copy
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.
This man page is correct for version 3.0.25 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.
