The following backup programs are available:

This section describes the differences, advantages, and disadvantages of the individual programs. The SAP program BRRESTORE is available for restoring files which were backed up with BRBACKUP/BRARCHIVE.

 

Note

We recommend deleting the environment variable ORACLE_HOME for the database upgrade to Oracle 8.1.X. However, in this case the backup with older versions of BRBACKUP or BRARCHIVE terminates with the following error message:

BR152E Environment variable ORACLE_HOME is not set

The problem occurs in particular with Business Warehouse 2.0, where Oracle 8.1 is used as a default.

For more information about solving this problem, see SAP Note 309322.
