 summary: Best Practices for Monitoring TiDB Using Grafana. Deploy a TiDB cluster using TiUP and add Grafana and Prometheus for monitoring. Use metrics to analyze cluster status and diagnose problems. Prometheus collects metrics from TiDB components, and Grafana displays them. Tips for efficient Grafana use include modifying query expressions, switching Y-axis scale, and using API for query results. The platform is powerful for analyzing and diagnosing TiDB cluster status.

 title: TiDB Backup & Restore Overview
 summary: TiDB Backup & Restore (BR) ensures high availability of clusters and data safety. It supports disaster recovery with a short RPO, handles misoperations, and provides history data auditing. It is recommended to perform backup operations during off-peak hours and store backup data to compatible storage systems. BR supports full backup and log backup, as well as restoring data to any point in time. It is important to use BR of the same major version as the TiDB cluster for backup and restoration.

 summary: TiDB supports backup storage to Amazon S3, Google Cloud Storage, Azure Blob Storage, and NFS. You can specify the URI and authentication for different storage services. BR sends credentials to TiKV by default when using S3, GCS, or Azure Blob Storage. You can disable this for cloud environments. The URI format for each storage service is specified, along with authentication methods. Server-side encryption is supported for Amazon S3 and Azure Blob Storage. BR v6.3.0 also supports AWS S3 Object Lock.

 summary: TiDB provides snapshot and log backup solutions for specific use cases, such as timely data recovery and business audits. To use point-in-time recovery (PITR), deploy a TiDB cluster >= v6.2.0 and update BR to the same version as the TiDB cluster. Configure backup storage on Amazon S3 and set a backup policy to meet data loss and recovery requirements. Run log and snapshot backups, and use PITR to restore data to a specific time point. Clean up outdated data regularly. For detailed steps, refer to TiDB documentation.
