So, I'm not super clear on how to do this.
the backup roots are not really a way to go back in time, they're just
the same data that maybe didn't get written, so you can maybe go to the
last revision if all the roots are not up to date, correct?
If so, is it best to get the last root since it's the one most likely to
be the oldest?
More generally do I do a check -b to see if that looks clean, and if so,
what's the command to replicate that root onto all the other roots?
Thanks,
Marc
