File Storage

Ar.io gives teams a durable file path for data that must remain accessible and intact over time. Files published through the network have a permanent source record on Arweave, while independent gateways can cache and serve useful copies.

This is useful for legal records, business documents, research materials, historical archives, and other data that needs an independent access path.

Why files need an independent access path

Most enterprise data is not lost because it is destroyed. It becomes unavailable because systems fail, infrastructure is compromised, or access is blocked elsewhere.

ar.io preserves an immutable source record and provides more than one way to retrieve it across outages, ransomware incidents, vendor changes, and operational disruption.

File preservation capabilities

Ransomware-resilient data access

Files published through ar.io become immutable records. A compromised operational system cannot encrypt or overwrite the permanent source, so teams retain a clean version to retrieve.

Resilient long-term access

ar.io separates file access from individual systems, contracts, or providers. Independent gateways keep the permanent source reachable as surrounding infrastructure changes.

Immutable records for compliance and trust
Once stored, a record remains exactly as it was when published. Teams can verify retrieved bytes against that permanent source during audits, investigations, or recovery.

Upload paths for files and datasets

ar.io supports small files and larger datasets through console, API, and bundling workflows.

Operational flexibility and integration

ar.io APIs and tooling fit into existing workflows, automation pipelines, and data management systems without replacing the operational system.

Resilient access without single points of failure

Independent ar.io gateways can maintain cached copies and provide multiple retrieval paths. Applications can switch gateways or operate their own instead of depending on one provider.

Who this is for

• Enterprises protecting mission-critical records
• Legal, financial, and compliance-driven organizations
• Healthcare, research, and public-sector institutions
• Companies strengthening ransomware recovery options
• Teams responsible for long-term data continuity

What access failure costs

Ransomware, outages, and infrastructure failures often block access even when data still exists. Organizations that cannot restore clean records face stalled operations, legal exposure, and difficult investigations.

With ar.io, critical files retain an immutable source and independent gateway paths.

Preserve files with self-service tools

Use the ar.io Console to upload permanent data, or use the developer documentation to integrate permanent records into an existing workflow.
