2. Use the arrow button to select a Server name. If you want to read a backup label from a backup

performed to a client’s local tape drive, select the “local (client tape)” option at the top of the list.

In this case, the Original Client (owner) field will change to Client Name, and a new field, Device

Name will appear.

3. If you selected a TSM Server, use the arrow button to select the Original Client (owner). All

backups are stored on the server in a TSM filespace specific to each client, so you must know the

original client (node) the backup was created for.

4. If you selected local (client tape) in the Server name field, you must select the Client Name and

the Device Name (SBTAPE) from which to read the backup in the fields provided.

5. Press the Select button next to the Backup ID field to display a list of backup images on the

server for the client. If the icon next to the label is yellow, this indicates that there is no backup

Label ID on the admin system for that backup. Select a backup image from the list to read.

6. Select the Read Label button.

The backup is read and the label information will be displayed if it exists.

If the label information for the backup is not found on the admin system, an error message will appear. This

indicates that the label was

expired, so no detailed information on the tape contents is available. Normally,

the backup is removed from the TSM server when a backup is expired. Sometimes, however, the label may

have been accidentally deleted from the admin system. If this is the case, you will need to rebuild the

backup label. Refer to

Rebuild (unexpire) a Backup Label for more information.

Expiring a Backup

TSM backups may become obsolete and need to be occasionally removed to free space on the server. This is

referred to as "expiring" a backup. When backups are no longer valid it is necessary to get rid of the backup

label and backup status information.

By default, the

Backup Retention Policy prevents TSM backups and backup tapes associated with a current

backup label from being overwritten by new backup jobs. When a backup is expired, the label information is

destroyed and the backup is removed from the server. In the case of tapes, the tape is not affected, but may be

overwritten by a new backup. For TSM server backups, the overwrite policy determines if backup jobs should

overwrite an existing backup or create an additional backup on the server. For tape backups, the overwrite

backup determines whether a tape containing a current backup label may be overwritten.

If a local tape backup has been expired or the label history has been inadvertently

removed from the system, it is still possible to rebuild this information. Refer to

Rebuild (unexpire) a Backup Label.

Very important note: If you expire a backup from the TSM server, the actual backup

will be removed from the TSM server. You are given ample warning before the

backup is removed, and once it has been remove it will no longer be possible to

access that data.
