How to see what active backup exist with onbar?

Hello everybody. I have onbar and tsm. I am using onbar to take backups. I used "onsmsync -g 10" to have 10 generations different of my backup. But I don't know to see these generations are active or expired. In sysutil database exist bar_action, bar_instance, bar_object, bar_ordertab and bar_server tables, but I can not determinate if the backup is active or expired. In the manual exists a table bar_syncdeltab, but in the instance does not exist. In the emergency boot file I can´t see if a backup is active or expired. Anybody know how to consult this information? Thank a lot Regards Servio Velasco
