i2Availability delivers near-zero RPO through real-time, incremental replication at both the byte level (for files) and the log semantic level (for databases). It captures data changes instantly on the primary server and synchronizes them to the standby node using synchronous or quasi-synchronous modes. This ensures transaction-level consistency, with ordered log replay preventing data inconsistencies across database systems.
To further enhance reliability, i2Availability uses local log caching and breakpoint resumption to handle network interruptions without data loss. In the event of a primary node failure, the system attempts to retrieve and replay any remaining unsynchronized data before initiating failover. This combination of continuous replication and final data reconciliation minimizes data loss at the point of failure, effectively achieving an RPO close to zero.
