That sounds like it might be the cause of the problem;  Our backup schedule
is pretty much active 24 hours a day, 7 days a week.  At night we run the
usual plethora of system backups but in the wee hours of the morning we
split off a mirror of a 2.5Tb database and its backup takes the better part
of the day (mixed with steady stream of Oracle archive logs) until the whole
process repeats itself come evening time.
To eliminate further confusion as to how the NB database backup is
configured, here is the output of bpsyncinfo:

Paul

Make sure you don't have any ACTIVE backups that are hanging around for
days.  If a scheduled backup completes but others are running then the
catalog backup will not take place.  The catalog backup will only run when
the NBU environment is inactive.

On any given day we typically run upwards of 450 jobs through the scheduler;
In spite of what we feel are high failure rates (roughly one every other
day), the majority of the runs go through without a hitch.  The
configuration tool states my NB database backup schedule options are:
        1) Never (i.e. manual)
        2) After each succesfull schedule
        3) After each succesfull archive
We currently use option 2.  But I am not seeing any NB backup activity for
weeks on end!  How can this be?  What constitutes a successful schedule?

A successful backup session means that at least one of the backups
which ran was successful.  A single backup failure does not cause the
NBU database to not get backed up.

If all backups fail, the NBU db backup doesn't execute, which makes
sense since there's effectively no new info in the db.
