delta-syncrepl and accesslog backup

Hello all,

I am migrating to delta-syncrepl and have a couple questions.

I currently back-up my data.mdb file for restore purposes (using mdb_copy). Now that I am using delta-syncrepl, do I also need to be concerned with the accesslog data.mdb file in the event of a restore?

What is the sync behavior of a consumer if it is configured to use delta-syncrepl and the provider is restored but not the accesslog?(i.e. the accesslog would be new on initial start of slapd after a restore)?

Files in question: /var/lib/ldap/data.mdb /var/lib/ldap/accesslog/data.mdb

Thanks for any input, Paul
