Virtualmountpoint

Authorized User

The virtualmountpoint option defines a virtual mount point for a file system if you want to consider files for backup that begin with a specific directory within that file system. Using the virtualmountpoint option to identify a directory within a file system provides a direct path to the files you want to back up, saving processing time. It is more efficient to define a virtual mount point within a file system than it is to define that file system using the domain option, and then to use the exclude option in your include-exclude options list to exclude the files that you do not want to back up.

Use the virtualmountpoint option to define virtual mount points for multiple file systems, for local and remote file systems, and to define more than one virtual mount point within the same file system. Virtual mount points cannot be used in a file system handled by automounter. Use the AFS/DFS backup clients to process virtual mount points for AFS/DFS file systems.

Note:
If the directory that you want to specify as a virtual mount point is a symbolic link, set the followsymbolic option to Yes. If that option is set to No (the default), you are not permitted to use a symbolic link as a virtual mount point.

After you define a virtual mount point, you can specify the path and directory name with the domain option in either the default client options file or on the incremental command to include it for incremental backup services. Users can also specify the path and directory name of the virtual mount point with the domain option in their own client options files and on the incremental command.

Supported Clients

This option is valid for all UNIX clients. The Tivoli Storage Manager Client API does not support this option.

Options File

Place this option in the client system options file dsm.sys.

Syntax

   .- ---------------------------.
   V                             |
>>---VIRTUALMountpoint directory-+-----------------------------><
 
 

Parameters

directory
Specifies the path and directory name for the directory you want to use as the virtual mount point for a file system. You cannot use wildcard characters in either the path or directory names.

Define only one virtual mount point with each virtualmountpoint option that you include in your client system options file. Use the virtualmountpoint option as many times as necessary to define all of the virtual mount points that you want to use.

Examples

Options file:
virtualmountpoint /afs/xyzcorp.com/home/ellen/
virtualmountpoint /afs/xyzcorp.com/home/ellen/test/data/

Command line:
-virtualmountpoint=/afs/xyzcorp.com/home/ellen/

This option is valid only on the initial command line. It is not valid in interactive mode.
