Correct procedure to backup LDAP?

[Jeff Grant <jgrant@voicesignal.com>]

Hey all.

I work at a medium-sized software company and we're about 70-100 users
big now.

We have 2 LDAP servers, and they need to be backed up regularly, *while*
LDAP is running - if possible.

I've seen 'slapcat' as a solution, but I've also read that it's not a
good idea to run this command while LDAP is running.

Is there a proper/functional one-liner that will allow me to backup LDAP
hot, and if not, what's a tried and tested way to do this backup?

Thanks.

-Jeff
