Matt - There isn't a conceptual problem with "starting early" in that
the Backup Stgpool operation is incremental, and so doing it again
later will get what hasn't already been copied to the Copypool.
A consideration in general would be that related data might be spread
more widely in the Copypool and thus cause any recovery of specific
filespaces using that data to take a bit longer. But that's not much
of a real issue in that recovery would use multiple days' worth of
Copypool imagery anyway, which is quite spread out as it is.
In that you're talking about backing up a disk storage pool, you should
be able to do that in parallel with incoming data, without much contention.
The overriding issue is that your DB backup be done at such a time as
to make your system fully recoverable.
