I assume nbackup would have the same side effect? It's tempting to make
an incremental backup every hour, but I'd hate to flush the working set
in the page cache every time.

It's not feasible to circumvent the page cache. It _might_ be possible
(not easy) to limit the number of pages a particular query can use, or
identify a massive serial read and restrict it to a few data pages at a
time. It will still need pointer pages, etc.
