:FWIW, I use Matt's -C option in production RELENG_4[_x] backups (about 15
:nachines) on a regular basis since his original posting to -stable (or was it
:-hackers?) -- thanks Matt! -- and it's really useful. I'd never test it on a
:memory-stressed machines, though.

You are welcome! I've been using it for my own backups since then
as well. And on -current, with snapshots (dump -L), the cache can
be safely used even if the filesystem is being actively modified.
(Though it should be noted that without snapshots, 'dump' cannot be
used to create a safe backup of a live system that is undergoing
change, whether the cache is turned on or not).
