They are identical (or should be).
I've recovered a slave after hard drive failure several times simply by
stopping slapd on a different slave, and then copying the database from
that replica to the one with the new hard drive (note that you want to
run db_recover after stopping slapd, before copying over the files).
To make db_recover update the *.bdb files from the log? I know it's
on startup, but I would've thought that a sync would have been done on
shutdown, too. That explains a couple of things I've seen...
On a clean shutdown a full checkpoint/sync will also occur, yes.
