Read the documentation at sleepycat -- the logs are per BDB 
environment.  In this case, it protects only the various BDB files used 
by Cyrus.

Correct, although you might care about the BDB logs if the mailboxes.db 
was corrupted due to the crash.  Personally I like dumping the mailbox 
list to a text file just before the backup as a belt-and-suspenders 
safety net.
