MinIO + S3 Backup Stack

Produktionsreife, selbstgehostete KI-Inferenz-Stack mit Ollama, Open WebUI und LiteLLM — einheitlicher API-Gateway, GPU-beschleunigte Inferenz und ein ChatGPT-kompatibles Chat-Interface.

S3-compatible object storage with automated backup, lifecycle management, and Nginx reverse proxy. Ideal for application data, backups, logs, and media — any workload that needs durable, scalable storage without the AWS bill.

What's Included

Includes: MinIO Server, Nginx reverse proxy, backup agent, mc client

Components:

• MinIO Server with S3-compatible API — drop-in for AWS S3, Backblaze, Wasabi
• Nginx reverse proxy with TLS, rate limiting, and large upload buffering (5GB+)
• Automated backup to remote S3 using mc mirror (incremental sync)
• Bucket lifecycle policies, versioning, and retention rules
• Web console for management and monitoring
• Health checks and automated recovery

Deployment Modes

| Mode | Use Case | Nodes | | ----------------------- | -------------------------- | ------------ | | Single-node standalone | Dev, personal use, <5TB | 1 | | Single-node with drives | Small team, HA storage | 1 + 4 drives | | Distributed cluster | Production, multi-AZ | 4-16 nodes |

The included stack ships as single-node with drives — ready to scale to distributed when needed. MinIO's erasure coding provides RAID-like protection without hardware RAID.

Backup Strategy

Recommended backup schedule:

• Hourly: Application data and active files (incremental)
• Daily: Full bucket sync to remote S3 or Backblaze B2
• Weekly: Lifecycle transition to archival storage
• Monthly: Immutable snapshot for compliance

The mc mirror command handles incremental sync efficiently:

mc mirror --watch /data/files play/mybucket

Cost Comparison

For 10TB monthly storage with egress: | Provider | Monthly Cost | |----------|-------------| | AWS S3 Standard | ~$230 | | MinIO self-hosted (4x 4TB NVMe) | ~$60 (amortized hardware) | | Backblaze B2 | ~$60 |

Self-hosted MinIO breaks even at approximately 5TB and gets cheaper from there.

Who This Is For

Developers and ops teams who need S3-compatible storage without monthly egress bills. Ideal for backup targets, media storage, log archives, and application data that needs to stay within a private network boundary.
