Using Labeled Tapes With Backup and Restore
Using Labeled Tapes With Backup and Restore
If labeled-tape processing is enabled for your system, you can use Backup and Restore
with both labeled and unlabeled tapes.
To access a file on a labeled tape, you must use a TAPE DEFINE — a named set of
attributes and values that specifies information about a tape file such as the volume ID,
tape density, and operator mount messages.
Backup can use all the listed attributes in a TAPE DEFINE for labeled tapes. Restore,
however, can use only DEVICE, MOUNTMSG, SYSTEM, and VOLUME. If your
DEFINE contains other attributes, Restore ignores them.
For more information about DEFINEs and labeled tapes, see Section 6, Creating and
Using DEFINEs , and Section 10, Using Labeled Tapes .
