Backup failures

Backup failures in RayDB can occur due to various reasons, including insufficient storage, connectivity issues, or internal system errors. This guide helps diagnose and resolve common backup failures.

Common Causes of Backup Failures

Insufficient Storage

• Backups require additional storage beyond the allocated database space.
• Solution: Increase the storage capacity of your cluster before initiating a backup.

Network Connectivity Issues

• Unstable network connections may disrupt backup processes.
• Solution: Ensure stable network conditions and retry the backup operation.

High Database Load

• Heavy workloads during backup execution can lead to timeouts or failures.
• Solution: Schedule backups during low-traffic periods or optimize database queries.

Internal System Errors

• Occasional internal errors can prevent backups from completing.
• Solution: Check the Backup Logs in the RayDB Dashboard for error messages and contact support if needed.

Troubleshooting Backup Failures

1. Check Backup Logs

   • Log in to the RayDB Dashboard.
   • Navigate to Backups → Backup Logs.
   • Look for error messages and timestamps to identify issues.

2. Verify Storage Availability

   • Ensure that your cluster has enough free space to store the backup.
   • Expand storage if necessary.

3. Retry the Backup

   • If the failure is due to a temporary issue, retry the backup manually from the Backups section.

4. Monitor Performance Metrics

   • Check database performance and CPU utilization before scheduling backups.

Best Practices to Avoid Backup Failures

• Enable Backup Alerts: Set up notifications to detect failures early.
• Perform Regular Test Restores: Validate backups by restoring them in a staging environment.
• Monitor Storage Usage: Prevent failures by ensuring enough storage is available.
