What is your QUERYSCHEDPERIOD option set to on your clients?  The default is 12 
hours, which means the client only checks twice a day to see what it's next 
scheduled event is.  So lets take the following scenario...  
A client was scheduled for a 10:00 pm backup.  It last checked with the server 
at 11:00 am, so it will not check again before it is scheduled to backup.  You 
change the association from the 10:00 pm schedule to a 8:00 pm schedule.  The 
client is not aware of this change unless you stop/start the scheduler so it 
will query the server and pick this up.  So when 10:00 pm come along, the 
client connects to the server, and then it finds out that it is no longer 
associated with the 10:00 pm schedule, so it will not backup, it queries to see 
what the next event is, and in this case, that would be 8:00 pm then next day.

Had you changed the schedule to a later time, say 11:30 pm, it would indeed 
pick up the change and backup that night.  But you may not always make the 
change to a later time.

We set all of our clients to query every 2 hours, this way most changes will 
get picked up.  You can go this by changing it in each OPT file on each client, 
or you can use CLIENT OPTIONSET on the server to send this out to all clients, 
but of course you will need to touch each node to do this also....

If you need more on this, let me know.

Why is it that anytime a client is removed from a schedule and added to a
different one the backup is missed? This always happens from my
recollection. No matter what the server version I have been it's happened.
The only way I've seen around this is to stop and start the scheduler on the
client after the client has been assigned to the new schedule.
