SMB shadow copies Windows users can independently access previous versions of files stored on SMB shares by using the Shadow Copies for Shared Folders client. After the Shadow Copies for Shared Folders client is installed on the user's computer, the user can access shadow copies for a share by right-clicking on the share to open its Properties window, clicking the Previous Versions tab, and then selecting the desired shadow copy. Users can view, copy, and restore all available shadow copies. Shadow Copies for Shared Folders preserves the permissions set in the access control list (ACL) of the original folders and files. Consequently, users can only access shadow copies for shares to which they have access. In other words, if a user does not have access to a share, he also does not have access to the share's shadow copies. The Shadow Copies for Shared Folders client pack installs a Previous Versions tab in the Properties window of files and folders on network shares. Users access shadow copies with Windows Explorer by selecting View, Copy, or Restore from the Previous Versions tab. (See Figure 23). Both individual files and folders can be restored. Figure 23 Client GUI When users view a network folder hosted on the storage system for which shadow copies are enabled, old versions (prior to the snapshot) of a file or directory are available. Viewing the properties of the file or folder presents users with the folder or file history-a list of read-only, point-in-time copies of the file or folder contents that users can then open and explore like any other file or folder. Users can view files in the folder history, copy files from the folder history, and so on. 140 File server management

SMB shadow copies

Windows users can independently access previous versions of files stored on SMB shares by using

the Shadow Copies for Shared Folders client. After the Shadow Copies for Shared Folders client is

installed on the user's computer, the user can access shadow copies for a share by right-clicking on

the share to open its Properties window, clicking the

Previous Versions

tab, and then selecting the

desired shadow copy. Users can view, copy, and restore all available shadow copies.

Shadow Copies for Shared Folders preserves the permissions set in the access control list (ACL) of

the original folders and files. Consequently, users can only access shadow copies for shares to which

they have access. In other words, if a user does not have access to a share, he also does not have

access to the share's shadow copies.

The Shadow Copies for Shared Folders client pack installs a

Previous Versions

tab in the

Properties

window of files and folders on network shares.

Users access shadow copies with Windows Explorer by selecting

View

Copy

, or

Restore

from the

Previous Versions

tab. (See

Figure 23

). Both individual files and folders can be restored.

Figure 23 Client GUI

When users view a network folder hosted on the storage system for which shadow copies are enabled,

old versions (prior to the snapshot) of a file or directory are available. Viewing the properties of the

file or folder presents users with the folder or file history—a list of read-only, point-in-time copies of

the file or folder contents that users can then open and explore like any other file or folder. Users can

view files in the folder history, copy files from the folder history, and so on.
