Automated MongoDB Backup System
Building a reliable backup pipeline with Go, mongodump, Drive uploads, and email alerts.
Automated MongoDB Backup System
Built an automated backup system for MongoDB with scheduled exports, Drive uploads, retention policy, and failure alerts.
Stack
- Runtime: Go
- Backup:
mongodump - Storage: Google Drive
- Scheduling: Cron
- Alerts: Email
Design
The exporter runs as a standalone binary. It dumps the target database, compresses the archive, uploads it to Drive, and keeps a local retention window. Failures trigger an email alert.
Challenges
- Keeping Drive uploads idempotent so reruns do not create duplicates.
- Managing memory usage during large dumps on a small VPS.
- Handling credential rotation without restarting the job.
Result
Reliable backups with verified restore tests and much less operational anxiety.
