So if i want to run database backup and archive logs backup in different time i must to use different policies, cause:
1. If i will use commulative backup there will be a lot of problems if full will be failed.
2. If i will use full for both, it is impossible to define which section of script (full backup or archive logs backup) due to run, cause NB_ORA_SCHED will not be set.
If NB_ORA_SCHED will be set, i may run database backup or archive logs backup depends of what automatic schedule was run.
