How to Send a 1TB Dataset Securely

Sharing large research datasets—genomics, medical imaging, HPC simulation outputs—requires more than just raw bandwidth. A 1TB file transfer demands careful attention to security, compliance, and operational best practices.

This guide walks you through the essentials of secure dataset sharing, from pre-transfer checklists to recipient management and tracking.

Common 1TB Dataset Scenarios

Large datasets are common in:

• High-Performance Computing (HPC): Simulation outputs, climate models
• Genomics & Bioinformatics: Whole genome sequences, protein databases
• Medical Imaging: MRI/CT scans, research cohorts
• Geospatial Data: Satellite imagery, LiDAR scans

Each scenario has unique challenges—PHI compliance, IRB requirements, export controls—but the transfer principles remain the same.

Security Checklist

Before you hit send, ask yourself:

1. Classify Your Data

• Is it public, internal, confidential, or restricted?
• Does it contain PII, PHI, or export-controlled information?
• What are your institutional/IRB obligations?

2. Access Control

• Who should have access?
• Do recipients need authentication?
• Should downloads be time-limited?

3. Retention Windows

• How long should the data remain accessible?
• What happens after expiry?

4. Auditability

• Do you need to track who downloaded what and when?
• Is there a compliance requirement for access logs?

Transfer Approach: Link vs Email Recipients

Email Delivery: Send a secure link directly to specific recipients. They receive an email notification and can download immediately.

Shareable Link: Generate a link and share it via Slack, Teams, or secure messaging. Anyone with the link can access (within your security parameters).

Best Practice: For sensitive data, use email delivery with expiry windows and download tracking.

Using Vouchers to Collect Files from Collaborators

Sometimes you need to receive large files, not just send them. This is where vouchers (file request links) come in.

How it works:

1. Create a voucher with specific parameters (size limit, expiry)
2. Send the link to collaborators
3. They upload files without needing an account
4. You receive and track all submissions

Use cases: Data collection from field sites, client deliverables, multi-lab collaborations.

Operational Tips

Naming Conventions

Use descriptive, versioned filenames:

• genomics_cohort_v2.3_2024-05-22.tar.gz
• simulation_run_12_output.zip

Checksums

Always include checksums (MD5, SHA256) so recipients can verify file integrity after download.

Documentation

Include a README file explaining:

• What the data contains
• File structure and formats
• Any preprocessing applied
• Contact information for questions

FAQ

Q: What are TeraSender's size limits?

A: Up to 1TB per transfer on premium plans. Free tier supports very generous limits compared to competitors.

Q: How long do download links remain active?

A: You control the expiry window—7 days, 30 days, or custom. Shorter windows reduce exposure risk.

Q: Can I see who downloaded my dataset?

A: Yes. Download tracking shows exactly when files were accessed and by whom (for email deliveries).
