Presumably because backup has previously only been described in
the FAQ-o-Matic.  But I'm pretty sure this has been the documented
backup method with the Berkeley DB backends since forever.  If that
doc is wrong, this warrants a warning in both the admin guide and the 
faq.

However, don't database recovery and restore of backup from DB + logs
do the same thing?  If so either both or neither should work.  Unless
the difference is that correct restore/recovery needs knowledge that
slapd has but the DB tools by themselves do not.

(In the latter case, maybe restore by starting a slap tool instead
of with db tools could work, I dunno.)

In terms of the Admin Guide, that in itself would just mean the section
should be moved.
