At the very least, you should be able to specify when your "backup day"
starts.
Hmmm. What about setting yourself to a different time zone? If you want a
window that starts at 20:00 and runs through 02:00, what if you told your
server it was in a time zone 4 hours earlier, and then set the window from
00:00 to 06:00?
Anyone have any thoughts about this?

Subject: RE: [Veritas-bu] Question on NBU scheduler....
Ok, understand. We had an issue using calaender based scheduling not
submitting jobs, and the Veritas Tech support gave this response which so
far has worked.
Hey, I'm happy to hear the performance is better. Calendar based
scheduling.... I do know the answer to this question. Ok, the answer is....
it runs on a 24 hour clock from midnight to midnight. Therefore if you look
closely, you will see the backup for today already ran in the wee AM hours,
and therefore will not launch at 18:00 hours.
Example:
M-th Incramentals run from 10pm-2:00am each day.
Monday - 10:00pm - window opens - backups start and complete
--2 hours later (midnight)it becomes Tuesday.... backup runs and completes
for Tuesday...
Tuesday - 10:00pm - window opens - nothing happens... (backups already ran
for Tuesday just after midnight...)
Tuesday night Midnight - (Officially Wednesday now) backups start and
fulfill Wednesday's backup requirement...
Etc..Etc...
I have spoken with Development about this many times. They say this
behavior is intended. Beats me as to why....

Yes, I applied the current patches, so I guess I'm at FP5.
(I still don't get the MP/FP thing...)
W.r.t. MPX and breaking out file systems.... I'm not talking about
keeping the drives STREAMING, I'm talking about having ANY job scheduled
on the drive AT ALL... (you first have to have a tape IN the drive
before you worry about performance/data transfer issues...) ;)
