Using Universal Naming Convention Names

A Universal Naming Convention (UNC) name is a network resource name for a share point on a workstation. The resource name includes the workstation name assigned to the workstation and a name you assign to a drive or directory so that it can be shared. The name you assign is also called a share point name.

Using UNC Names in Domain Lists

The following rules apply when using UNC names to specify a domain list. You must specify:

Example 1: To specify drive a: containing removable media, enter

domain a: \\local\c$

Example 2: To specify fixed drive c:, enter

domain c: \\remote\share1 \\remote\c$

Backing Up Specific Files Using the Universal Naming Convention

You can back up shared files in a network through the use of a UNC name. A UNC name is a network resource name for a share point on a workstation. The resource name includes the workstation name assigned to the workstation and a name you assign to a drive or directory so that it can be shared. The name you assign is also called a share point name.

Using a UNC name permits you to back up specific shared directories to a separate file space. This is useful if, for example, you or an administrator want to back up a small portion of data that you would otherwise be unable to access. Drives are not backed up to a separate file space.

On Windows NT and Windows 2000, every local drive is accessible via a UNC name except for drives containing removable media (such as tapes, cartridges or diskettes). Access these drives by using a predefined administrative share name consisting of the workstation name and the local drive letter, followed by $. For example, to specify a UNC name on drive c: for workstation ocean, enter:

\\ocean\c$

The $ sign must be included with the drive letter.

To enter a UNC name for workstation ocean and share point wave, enter:

\\ocean\wave 

When accessing files, you do not need to enter the letter of the drive except for drives containing removable media.

See Table 12 for examples showing selective backup of files using UNC names. In these examples, assume that:


Table 12. UNC examples

Example Comment
dsmc sel \\alpha1\c$\ name of remote file space is \\alpha1\c$
dsmc sel \\major\c$\ name of local, fixed file space is \\major\c$
dsmc sel a:\ name of local, removable file space is volume label of a:
dsmc sel \\alpha1\betarc\ name of remote file space is \\alpha1\betarc
dsmc sel \\alpha1\testdir\ name of remote file space is \\alpha1\testdir
dsmc sel d:\ name of local, fixed file space is \\major\d$
dsmc sel c:\ file space name is \\major\c$
dsmc sel r:\ file space name is \\alpha1\betarc

You can also specify UNC names for files in your include-exclude and domain lists; see Creating an Include-Exclude List (Optional) and Domain for more information.
