Backup and Restore 2 Manual—522696-019

Difference between BR and BR2
as a common interface for Backup Restore 2 (BR2) and Backup Restore (BR)
commands. However, the syntax of Backup and Restore commands for Backup
Restore (T9074) and Backup Restore 2 (T0744) must be entered in the BRCOM
prompt exactly as updated in the respective Backup Restore Utility Manuals. BRCOM
supports only basic Backup and Restore commands of Backup Restore (T9074) and
does not support any run options and features.
Difference between BR and BR2
File Types Supported
BR utility is used to back up and restore Enscribe and SQL/MP files. It is used to
perform volume mode backup and restore. Whereas, BR2 is used to back up SQL/MX
and OSS file objects.
File Types not Supported
BR does not support SQL/MX files and OSS file objects while, BR2 does not support
Enscribe and SQL/MP files. Hence, BR and BR2 cannot be used interchangeably. You
will need both BR and BR2, based on the file type you want to back up and restore.
Tape Formats
BR and BR2 use different tape formats. Therefore, you cannot combine Enscribe and
SQL/MP files with the OSS and SQL/MX files on the same tape.
Syntax
The syntax for BR2 is different from the syntax for BR. If you enter incorrect syntax for
file types supported by BR or BR2 at the BRCOM prompt, the command is not directed
to the appropriate Backup and Restore utility.
Explicit Wild Cards
BR2 does not support explicit wild cards for objects except for Catalogs *.
BR2 supports implicit wild cards for objects. If you specify a SQL/MX schema, all
objects under that schema are backed up or restored unless you exclude them. For
example:
If you specify the OSS directory /usr/home, all objects in the directory and all its
subdirectories are backed up or restored unless you exclude them.
If you specify the OSS directory /, the entire OSS file system is backed up or
restored.
Tape Attributes
BR processes all tape attributes. Whereas, BR2 ignores the following tape attributes:
