Tivoli Storage Manager for Macintosh Backup-Archive Client Installation and User's Guide

Backup Considerations

This section discusses some advanced considerations for using backup. You do not need to understand this information to use Tivoli Storage Manager for basic work.

How Tivoli Storage Manager Maintains Volume Names

Tivoli Storage Manager backs up volumes based on the volume name. Tivoli Storage Manager maintains each volume name as a separate restore or retrieve volume. These volume names become the names of file spaces on the server.

If you change the name of a volume you have already backed up, Tivoli Storage Manager sees it as a new volume and does not relate it to the previous one. An incremental backup on the volume backs up the files under the new name. A mismatch might occur if you rename your volumes, or if you access Tivoli Storage Manager from a different workstation than the one from which you backed up the files.

Volume Naming Precautions

Unlike other applications on the Macintosh, Tivoli Storage Manager is not case sensitive--it sees two volumes called "La Pomme" and "la pomme" as identical. Therefore, you must assign a different name to each volume to avoid volume duplications.

If duplicate volumes exist on your desktop, Tivoli Storage Manager cannot determine which one corresponds to the volume of the same name on the server, and displays an error message. Remove or rename duplicates as needed.

Backing Up Opened Files

Some files on your system may be in use, or open, when you try backing them up. Because an open file may change during a backup, the backup may not accurately reflect the contents of the file. If this is the case, you need to consider the following options:

File Sharing Access Privileges

Tivoli Storage Manager also backs up File Sharing Access Privileges, but only if all backups are done with File Sharing turned on. Also, to restore folders with their previous access privileges, you must perform the restore while File Sharing is on.
