After skipping through the DB docs I am sure you could write a book
about that... Therefore I'll just add some little notes.=20

Speaking about db_recover: Originally that was done automatically in
slapd. It was dropped exactly because data loss could result. Recovering
the database is risky in the sense that doing it twice at the same time
/will/ kill your data. AFAIK power loss during database recovery could
also result in complete data loss.=20

So basically you should backup your db before running recover. Which is
another good reason to not do it automatically.=20
