You can also specify UNC names for files in your include-exclude and domainlists.Related tasks“Creating an include-exclude list” on page 66Related reference“Domain” on page 346Microsoft Dfs file protection methodsThere are some methods that you can use to protect the data in your Microsoft Dfsenvironment.Here are the methods you should use to protect your Microsoft Dfs data:1. Back up the Dfs link metadata and the actual data at the share target of eachlink from the workstation hosting the Dfs root. This method simplifies back upand restore by consolidating all of the Tivoli Storage Manager activities on asingle workstation. This method has the disadvantage of requiring anadditional network transfer during backup to access the data stored at linktargets.2. Back up only the Dfs link metadata that is local to the workstation hosting theDfs root. Back up the data at the target of each link from the workstation(s)which the data is local too. This method increases back up and restoreperformance by eliminating the extra network transfer, but requires TivoliStorage Manager back up and restores to be coordinated among severalworkstations.Note:1. This feature applies to Windows Server 2003.2. See the product README file for current limitations of this feature.Files contained on a Dfs server component are accessed using a standard UNCname, for example:\\servername\dfsroot\where servername is the name of the host computer and dfsroot is the name of theDfs root.If you set the dfsbackupmntpnt option to yes (the default), an incremental backupof a Dfs root does not traverse the Dfs junctions. Only the junction metadata isbacked up. This is the setting you should use so that Tivoli Storage Manager canbe used to restore Dfs links.You can use the dfsbackupmntpnt option to specify whether Tivoli StorageManager sees a Dfs mount point as a Microsoft Dfs junction or as a directory.Important: Restore the Dfs junction metadata first. This recreates the links. Thenrestore each junction and the data at each junction separately. If you do not restorethe junction metadata first, Tivoli Storage Manager creates a directory under theDfs root using the same name as the junction point and restores the data in thatdirectory.The following example relates to method 1 above and illustrates how to use TivoliStorage Manager to back up and restore a Microsoft Dfs environment. Assume theexistence of a domain Dfs environment hosted by the workstation almaden:Chapter 4. Backing up your data 159
