Comparison With the BACKUP and
RESTORE Utilities
This appendix describes the differences between Backup and Restore 2 and the
BACKUP and RESTORE utilities (T9074). BRCOM (T2721), the interface to Backup
and Restore 2, coexists with the BACKUP and RESTORE utilities (T9074).
Unsupported File Types
Backup and Restore 2 does not support Enscribe and SQL/MP files. To back up and
restore Enscribe and SQL/MP files, continue to use the BACKUP and RESTORE
utilities (T9074). However, you can issue a BACKUP or RESTORE command for
Enscribe or SQL/MP files directly from BRCOM. BRCOM forwards the command to the
BACKUP and RESTORE utilities (T9074), which takes control of the terminal and
processes the command directly.
To back up Enscribe or SQL/MP files, regardless of whether you issue the command
from BRCOM or directly from TACL, you must use the syntax documented in the
Guardian Disk and Tape Utilities Reference Manual with these exceptions:

Commands for Enscribe and SQL/MP files entered at the BRCOM prompt must
terminate with a semicolon.

BRCOM does not support these run options:

DEFMODE


INLINE

INV

MAXMAINSTACKSIZE

MAXNATIVEHEAPSIZE


All other run options are supported as described in the TACL Reference Manual.
Note. The syntax for Backup and Restore 2 is different from the syntax for the BACKUP and
RESTORE utilities (T9074). If you enter the syntax incorrectly for each file type at the BRCOM
prompt, BRCOM might not be able to determine if the command needs to be forwarded to the
BACKUP and RESTORE utilities (T9074).
You must use the syntax documented in this manual for OSS and SQL/MX files. For Enscribe
and SQL/MP files, use the syntax documented in the Guardian Disk and Tape Utilities
Reference Manual. However, commands for Enscribe and SQL/MP files entered at the
BRCOM prompt must terminate with a semicolon.
