Tivoli Storage Manager for Windows Backup-Archive Clients Installation and User's Guide

Backing Up Microsoft Dfs Files

Note: This feature applies to Windows 2000 with NTFS file systems only.

Note:
Please see the product Readme for the most up-to-date capabilities and limitations of this feature.
If your organization uses the Microsoft Distributed File System (Dfs) server component for Windows 2000, you can back up and archive all your Microsoft Dfs files as a single file system, even if the files are on different servers and share points. Files contained on a Dfs server component are accessed using a standard UNC name, for example:
\\servername\dfsroot\

where servername is the name of the host computer and dfsroot is the name of the root file system.

If your organization uses the Microsoft directory services feature of Dfs, you can access a file system through either its fault tolerant domain name or its server name, for example:

\\default tolerant name\dfsroot\

where default tolerant name is a name your administrator has designated to specify a Microsoft Dfs server component stored in directory services, and dfsroot is the name of the root file system.

By default, an incremental backup of a DFS root does not traverse the Dfs junctions. Only the junction metadata is backed up.

You can use the dfsbackupmntpnt option to specify whether Tivoli Storage Manager sees a Dfs mount point as a Microsoft Dfs junction or as a directory. For more information on using this option, see Dfsbackupmntpnt.

To restore Dfs junctions and the data for each junction, restore the Dfs junction metadata first and then restore each junction separately. If the junction metadata is not restored, Tivoli Storage Manager creates a directory under the Dfs root using the same name as that of the junction point and restores the data in that directory.
