Backing Up Removable Media Using Labels

Tivoli Storage Manager backs up your removable media (such as tapes, cartridges or diskettes) based on the drive label, not the drive letter. If a drive has no label, the backup does not occur. This use of drive labels permits you to perform such tasks as backing up different diskettes from the a: drive.

For a restore or retrieve, Tivoli Storage Manager maintains a separate file space for each drive label. These labels become the file space names on the server. If you change the label of a drive you already backed up, Tivoli Storage Manager views it as a new drive and does not relate it to your previous drive.

Because Tivoli Storage Manager uses the labels to manage backups and archives of your removable media, you occasionally need to use those labels to locate data when using commands. For example, if you try to restore a file on diskette or CD-ROM using d:\projx\file.exe as a file name, Tivoli Storage Manager substitutes the current label of your d: drive for the d:. If the d: drive label is d-disk, d:\projx\file.exe becomes {d-disk}\projx\file.exe, and the label is enclosed in braces.

If the label of the d: drive does not match a file space name on the server, Tivoli Storage Manager cannot find your files. A mismatch between a label and a file space name might occur if you label your drives again, or if you access Tivoli Storage Manager from a different workstation than the one from which you backed up the files. If you have not relabeled the drive, and you are at the same workstation where the file was backed up, then you can use the drive letter as a shorthand version of the file space name (drive label).
