Using Scratch Tapes

You can use expired BACKUP, IBM, or ANSI labeled tapes for labeled tape BACKUP procedures.
If no expired tapes exist, you can create an ANSI or IBM labeled scratch tape using MEDIACOM.
NOTE: Scratch ANSI or BACKUP tapes can be used with LABELS BACKUP. Only scratch IBM
tapes can be used for LABELS IBMBACKUP.
If you want to use specific scratch tapes, specify the volume IDs in the VOLUME attribute of the
DEFINE. If any scratch tape will do, omit the VOLUME attribute from the DEFINE (or specify
SCRATCH) as its value.
NOTE: Do not confuse the DEFINE attribute VOLUME SCRATCH with the BACKUP option
SCRATCHVOL $volume. The VOLUME SCRATCH attribute refers to a tape volume; SCRATCHVOL
refers to a disk volume. Use the DEFINE attribute for labeled tape BACKUP procedures. Use the
BACKUP SCRATCHVOL option only during file conversion operations with nonpartitioned files or
individual partitions of partitioned files.

Examples

These examples demonstrate how to create CLASS TAPE DEFINEs and use them in BACKUP
commands. For more information on labeled-tape processing, see the Guardian User's Guide. For
