It isn't so much the Openldap version as the BDB version.

I'm going to stick my neck out here. You should be able simply to copy 
your single BDB log file to a backup directory. You can build a complete 
database from this log file and nothing else. I just did it, to check ;)

HOWEVER. If you have the Sleepycat BDB 4.1.24 docs (i.e. if you compiled 
your own,) read the following man pages before you do anything or allow 
yourself any feeling of being safe:

db_checkpoint
db_archive
db_recover (especially the '-c' option.)

By choosing BDB IMHO you've chosen the best and safest of the backend 
alternatives. However, 4.1.24 has bugs that have been corrected in 4.1.25.

HTH,

Tony
