OK, let me restate the question, since I think I should be clear in what
I'm trying to accomplish.

I want a consistent backup.  Is following
http://wiki.apache.org/cassandra/Operations (section "Backups")
sufficient?  Is there a danger that uncomitted data will not be
captured?  If so, what can I do (avoiding, if possible, a cluster
shutdown) to get a consistent view of the data?

I'm asking on the developer list to keep the thread in the same place
but this is probably a user-level question.

Ted
