Best Practices for Database Backup and Recovery
Automate Regular Backups
Schedule automated backups to ensure consistency and reduce human error. For example, perform full backups weekly and incremental backups daily.
Example: Use Tencent Cloud’s Database Backup Service (DBS) to automate backups for MySQL, PostgreSQL, or MongoDB with customizable schedules.
Store Backups in Multiple Locations
Keep backups in at least two geographically separate locations to prevent data loss from regional failures.
Example: Tencent Cloud’s COS (Cloud Object Storage) provides durable, cross-region replication for backup files.
Test Recovery Procedures
Regularly test backup restoration to verify data integrity and recovery time objectives (RTO).
Example: Simulate a failure scenario in Tencent Cloud’s TencentDB to restore a database from a backup and measure recovery speed.
Encrypt Backups
Protect sensitive data by encrypting backups both in transit and at rest.
Example: Tencent Cloud supports TLS encryption for data transfer and KMS (Key Management Service) for at-rest encryption.
Monitor Backup Health
Set up alerts for failed backups or storage issues to address problems proactively.
Example: Use Tencent Cloud’s Cloud Monitor to track backup job statuses and receive notifications.
Follow the 3-2-1 Rule
Keep 3 copies of data (1 primary + 2 backups), store on 2 different media, and keep 1 offsite.
Example: Combine Tencent Cloud’s DBS (backup) with COS (offsite storage) for compliance.
Document Recovery Plans
Maintain clear documentation for recovery steps, including roles and responsibilities.
Example: Tencent Cloud’s Database Disaster Recovery (DR) solutions provide guided workflows for failover scenarios.
Use Point-in-Time Recovery (PITR)
Enable PITR to restore databases to a specific moment before corruption or deletion.
Example: TencentDB for MySQL supports PITR with granular recovery options.
Limit Access to Backups
Restrict permissions to backup systems to prevent unauthorized modifications.
Example: Tencent Cloud’s CAM (Cloud Access Management) allows role-based access control for backup services.
Consider Multi-Cloud or Hybrid Strategies
For critical workloads, distribute backups across platforms to mitigate vendor-specific risks.
Example: Combine Tencent Cloud’s DBS with on-premises storage for hybrid resilience.
