The "db.backup1" and "db.backup2" dirs are created by obeying Sleepycat's 
recommendations on backing up Berkeley db to prepare for possible 
catastrophic recovery. If you have to restore everything from backup, using 
the latest clean version of the db.backup's is safer than trying to use the 
db/ directory as your backup software grabbed them (since your backup 
software might not have done it in the correct order).

Backup and disaster recovery (and really our interaction with Berkeley db 
as a whole) are things that need to be better documented.
