The bpstart_notify and bpend_notify scripts do not get called during a SQL database backup.
Details:
This issue is related to a limitation of the DBBACKUP.EXE process. During SQL backups, DBBACKUP.EXE is the process responsible for the backups. This process does not have the capability of calling thebpstart_notify and bpend_notify scripts; therefore, the scripts will fail to execute.
