Environment:      NBU 3.2
            Solaris 2.5.1 master with STK9714 library
            Solaris 7 client

I have an odd situation in which a full backup which I set up is running
twice, simultaneously. Shown below is the class definition. You will notice
that the "full" and "cinc" schedules have a frequency of "every 1 day" but
no windows at all. I actually invoke the "full" and "cinc" schedules with a
cron job that runs Saturday morning at 8:00. The cron job executes a script
which determines the day of the month, selects the "full" schedule for the
first Saturday and the "cinc" schedule for other Saturdays, then executes
the command

      bpbackup  -i -c vault -s $SCHEDULE -k "${KEYWORD}"

I expected three jobs to be created this past Saturday, one for each of the
new streams. But six jobs were started instead. Two jobs for each of the
file systems and both of the jobs backed up the entire file system, so I
got double the backups, and it took a whole lot longer than it should have.
Three of the jobs were writing to one tape drive while the other three
wrote to another tape drive, like so

      home200 + home201 + home202  ---> MPX ---> drive 1

      home200 + home201 + home202  ---> MPX ---> drive 2

The backups ran fine, each job backed up the identical number of bytes, and
each set used 7 DLTIV cartridges for a total of 14. But like I said
already, it took a long time and my management is going to get cranky if I
keep using so many tapes.

Has anyone ever seen this happen? What might be causing this? It does not
happen with the daily incremental backups.
