What Data for This Category Looks Like
Data for this category originates from backup systems, database logs, object storage, and disaster recovery platforms. Update frequencies fall into three groups: daily, monthly, and quarterly. Daily deliverables include backup policies, recovery drill reports, disaster recovery switchover plans, and data verification records. Core fields include backup timestamp, recovery duration, data consistency verification results, drill participation flags, and storage paths. All data must be linked to specific database instances and business system identifiers. No unified standardized field format exists. Collection rules must be adjusted to match individual deployment environments.
Constraints Imposed on the Database and Operations Link
Since data sources cover heterogeneous systems, the database and operations link must support multiple types of database connection protocols. This ensures backup, drill, and verification processes can read data across systems. Different update frequencies require the operations link to configure layered scheduling policies. These match the execution rhythms of daily backups, monthly drills, and quarterly plans. The most time-consuming steps—recovery point confirmation, drill script execution, and data consistency verification—generate large numbers of concurrent database read and write requests. Connection pool and cache resources must be configured appropriately to avoid exhausting database resources and interrupting processes. Additionally, data verification results must be written to storage in real time. This places clear requirements on database persistence capabilities.
How to Configure Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| MongoDB Connection Address | mongodb://username:password@host:port/dbname?authSource=admin | Matches FastGPT v4.17.0 official MongoDB connection format, adapts to containerized local or remote MongoDB instances |
| PostgreSQL Connection Address | postgresql://username:password@host:port/dbname | Used to connect to PostgreSQL-type backup metadata databases, compatible with standard PostgreSQL connection protocols |
| Maximum Database Connections | 20–30 connections | Adapts to single-node 4c16g hardware configurations, prevents exhausting database connection pool resources from concurrent drill and backup requests, and mitigates service overload in high-concurrency scenarios |
| Redis Connection Address | redis://:password@host:port/0 | Used to cache drill verification results and backup status, reduces repeated database query pressure, and improves execution efficiency of data consistency verification |
| Backup Timeout Threshold | 300–600 seconds | Matches typical disaster recovery drill execution durations, prevents single drill processes from being interrupted due to timeout |
| Verification Result Cache Duration | 86400 seconds | Matches daily backup update frequencies, reduces resource consumption from repeated verification |
Three Common Misconfiguration Scenarios
- Scenario: FastGPT service fails to start, with a database connection verification failure prompt. Cause: MongoDB or PostgreSQL connection addresses are not configured correctly, or corresponding connection parameters are not updated after database migration. This prevents the service from reading backup metadata.
- Scenario: Frequent database connection timeout errors occur during disaster recovery drill execution, interrupting drill script runs. Cause: Maximum database connections are set too low. Concurrent drill requests exhaust database connection pool resources, triggering connection refusals.
- Scenario: Backup recovery verification records cannot be displayed normally, with empty data shown on the page. Cause: Redis connection address is configured incorrectly. The cache middleware cannot connect normally, preventing verification results from being read and displayed properly.
How to Verify Successful Configuration
- Run the built-in startup verification command of the FastGPT service. Check whether the connectivity status of databases and cache middleware is normal.
- Manually trigger a small-scale disaster recovery drill. Observe whether database read and write operations complete smoothly during the backup recovery process, with no error messages.
- Review database logs. Confirm there are no frequent connection timeout or connection refusal errors. Verify the rationality of connection pool configurations.
- Access the corresponding table in the backup metadata database. Confirm that drill reports and verification records have been written correctly, with data formats matching expected standards.
