Now, my colleague doesn't agree with me on the delta-syncrepl approach, and prefers to update A and B independently. His argument is that with delta-syncrepl, B is dependent on A, so if A's databases (main + log) are corrupted, and we have to restore A to a previous checkpoint, B would automatically rollback, and we would lost the latest data. I still prefer delta-syncrepl approach, since if updated independently, A and B can be out-of-synch over time and we wouldn't know it.
If A corrupts, then you slapcat B and reload A with the data. --Quanah -- Quanah Gibson-Mount Principal Software Engineer Zimbra, Inc -------------------- Zimbra :: the leader in open source messaging and collaboration
