HP BACKCOPY User Manual

Labeled Backup Tape Volume Labels
For labeled backup tapes, BACKUP writes either an IBM volume label or a customized ANSI volume
label (the BACKUP label) at the beginning of the tape.
• The initialized IBM tape, as defined by the IBM-MVS standard, contains:
A beginning-of-volume label (VOL1)◦
◦ A beginning-of-file-section label (HDR1)
◦ A tape mark
• The initialized ANSI tape, as defined in the ANSI standard, contains:
A beginning-of-volume label (VOL1)◦
◦ A beginning-of-file-section label group (HDR1, HDR2)
◦ Two tape marks
◦ An end-of-file label group (EOF1,EOF2)
◦ Two tape marks
NOTE: The BACKUP label type is a customized version of the ANSI label. The labels are identical
except character 80 (from the BACKUP label) is a B instead of a 3. When BACKUP writes to a
scratch ANSI labeled tape, it changes it into the BACKUP label type.
Following this volume label, BACKUP writes all labeled backup tapes in tape format 3. Therefore,
the files on a labeled backup tape are not in the standard labeled tape format (ANSI or IBM).
Using DEFINEs for Labeled Backup Tapes
You must specify a CLASS TAPE DEFINE (instead of a tape device name) in the BACKUP command
to use a labeled backup tape. You create the DEFINE in the same way you create DEFINEs for
ANSI and IBM labeled tapes. If you are not familiar with labeled-tape processing on NonStop
systems (or with DEFINEs), see the Guardian User's Guide. It gives instructions on using different
DEFINEs including CLASS TAPE DEFINEs for labeled-tape processing.
The two differences between using TAPE DEFINEs for backup labeled tapes and for ANSI and IBM
tapes are:
• You can use only a subset of the CLASS TAPE attributes for a backup labeled tape. The
supported attributes are summarized in Table 11. For a complete description of these DEFINE
attributes, see Appendix E: CLASS TAPE DEFINEs.
• You must specify the LABELS attribute as either BACKUP or IBMBACKUP.

used.
