MinIO-Based Efficient Database Backup and Synchronization Strategy: Compressed and Encrypted Storage with Cross-Region Real-Time Synchronization

Abstract

This paper presents a MinIO-driven database backup and synchronization framework that tackles legacy issues like slow backups, costly storage, and cross-region sync gaps. By merging LZ4 compression (73.5% size reduction) with AES-256-GCM encryption, the system slashes storage needs while hardening security. MinIO’s Webhook system keeps local and remote backups in lockstep—even during network outages—through real-time sync. Tests on an i5-11400/8GB setup showed consistent 80+MB/s uploads and 380+MB/s downloads, proving MinIO’s ability to handle rapid transfers. While the strategy excels under typical loads, scaling to high-traffic environments requires tuning. Next-phase work will streamline encryption workflows and boost concurrency handling for broader enterprise adoption.
