You have apparently missed the fact that rsync (unless you go out of
your way to defeat this) will copy to a temporary filename, and then
mv the new file in place of the old. This doesn't modify the old
file; it unlinks the copy you are replacing, leaving any other
directory entries which point at the old data unaffected.
Ahh, there's the subtlety that I missed. :-) I figured I was missing
something, since at face value it seems like your hard link strategy is
doomed to fail.
Thanks for the clarification :-) That's a pretty nifty mechanism to
retain your old database versions. I suppose you just have to be
careful to make a copy of the cluster before trying to start it up (lest
you break an older or newer backup).
