## Conclusion

Through the three practices above, we have validated the high availability of the TiDB DR Auto-Sync deployment solution, ensuring no data loss even in the event of a data center-level failure.

Especially in FSI, many clients operate in two data center environments for high availability. TiDB introduces the DR Auto-Sync (Data Replication Auto Synchronous) mechanism to address the two data center deployment challenges, ensuring data consistency while enhancing system availability.
