TiDB’s integrated capabilities for backup and restoration form the backbone of its disaster recovery prowess. Leveraging tools like Backup & Restore (BR), TiDB simplifies the process of creating full snapshot backups at specific time points and ensures continuous log backup of the cluster. The ability to restore from either snapshot or PITR (Point-In-Time Recovery) log files within a new region or cluster is particularly beneficial during catastrophic failures where primary data centers might be compromised.
The automated backup features allow users to plan regular backup intervals that are seamlessly executed, reducing manual intervention and the potential for human error. Starting from version 6.5.0, TiDB also allows restoring from EBS volume snapshots, a feature especially useful for cloud-native environments running on platforms like Kubernetes. This flexibility ensures that your data is safe, recoverable, and adheres to your organizational RPO objectives, effectively forming a robust last line of defense against data loss.
High Availability and Fault Tolerance Features
TiDB’s commitment to high availability and fault tolerance is evident in its architecture and operational features. The system’s design, which separates storage and compute layers, facilitates efficient scaling and operational resilience. By storing multiple replicas of data and implementing sophisticated load balancing, TiDB guarantees data availability even in the face of network or hardware failures, thus eliminating single points of failure.
The integration with TiCDC enhances TiDB’s fault tolerance by enabling real-time replication of incremental data changes, thereby maintaining data consistency across diverse failure scenarios. TiCDC’s ability to manage and dynamically adjust to changes without service interruption ensures that data is continuously available to downstream systems for disaster recovery purposes.
