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

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
, 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 When backups are no longer valid it is necessary to get rid of the backup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
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.
