Saludos desde Maracay, Venezuela.
Aunque puede haber cambiado algo con la versión te envío...
Comando general de Backup...
dbbackup -c "eng=sample_server;dbn=asademo;uid=dba;pwd=sql"
La primera vez se hace respaldo del DB y del log, luego...
Para hacerlo incremental despues en realidad solo se respalda el log...
Del Manual: Opciones -n -t
Change backup transaction log naming convention (-n) This option changes the naming convention of the backup transaction log file to yymmddxx.log, where xx is a number from 00 to 99 and yymmdd represents the current year, month and day. By default, the name used for the backup transaction log file is identical to the file name of the transaction log that is being backed up.
When using the -n option, you must also use the -r or -t options.
Back up the transaction log file only (-t ) This can be used as an incremental backup since the transaction log can be applied to the most recently backed up copy of the database file(s).
Espero que te sirva..
