Maybe I can answer to follow-ups at once. Easy one first:

I don't think spooling will solve my problem. First off, I'm using disks
as my storage, not tapes; spooling is not recommended. Second, the
bottleneck clearly (well, clearly to me) is at the client side choosing
files. Note that Bytes/sec is under 8,000. I don't have any currently-
running backups to compare it to, but that seems like an *extremely* low
number.

No, I do not. At least, not on purpose, and not that I can see.
Although I did just notice that it's VSS, if that matters.

JobId 272 Job CEFiles01Backup.2011-04-18_23.05.00_41 is running.
VSS Incremental Backup Job started: 18-Apr-11 22:36
Files=71,586 Bytes=273,451,803 Bytes/sec=7,131 Err...

ors=0
Files Examined=15,267,990

But if it's already just using timestamp, then I may just be stuck with
a 12-hour incremental.
