AWS Snow Family: How to Transfer Massive Data to AWS Offline

Key Takeaway

AWS Snow Family consists of physical devices for data transfer when network connectivity is limited or when moving massive amounts of data. Capacity increases from Snowcone (smallest) to Snowball Edge (medium) to Snowmobile (largest), with edge computing support included.

When Should You Use Snow Family?

Best For

Snow Family Recommended Scenarios:
├── Limited network bandwidth
│   └── Slow or unstable internet connection
├── Petabyte-scale data
│   └── Online transfer would take months or years
├── Remote/disconnected environments
│   └── Mines, ships, military bases
├── Edge computing requirements
│   └── Data collection + on-site processing
└── Data center closure/migration
    └── Bulk migration of entire data

Not Ideal For

Cases Where Snow Family Isn't the Best Fit:
├── Sufficient network bandwidth
│   → DataSync (online transfer is faster)
├── Regular/continuous sync
│   → DataSync + scheduling
├── Small data volumes (few TB or less)
│   → aws s3 cp or DataSync
└── Real-time data access needed
    → Storage Gateway

Decision Flow

Data Migration Service Selection:
        │
        ▼
Sufficient network bandwidth?
        │
       Yes → Data volume?
        │         │
        │     ≤ Few TB → [aws s3 cp / DataSync]
        │         │
        │     Tens of TB~PB → [DataSync + Direct Connect]
        │
       No (Network limited)
        │
        ▼
Data volume?
        │
    ≤ 14 TB, portable needed → [Snowcone]
        │
    Tens~hundreds TB → [Snowball Edge]
        │
    10+ PB → [Snowmobile]

Transfer Time Comparison

3. ✅ Exabyte-scale data: "Migrate entire datacenter, 100 PB" → Snowmobile
4. ✅ Device order: Smallest to largest → Snowcone, Snowball, Snowmobile
5. ✅ DataSync combination: "Initial bulk + continuous sync" → Snowball + DataSync

Current Status

Device	Status
Snowcone	No new orders (Nov 2024)
Snowball Edge 80TB	Discontinued
Snowball Edge 210TB	✅ Available
Snowball Edge Compute 104 vCPU	✅ Available
Snowmobile	Case-by-case consultation

Alternatives: New customers are directed to AWS DataSync, Direct Connect, or AWS Partner solutions.

Frequently Asked Questions

Q: How do I choose between Snowball Edge and DataSync?

Decide based on network conditions. With sufficient bandwidth, use DataSync. With limited network or very large data, choose Snowball Edge.

Q: Can I process data directly on Snowball Edge?

Yes. You can run EC2 instances and Lambda functions on Snowball Edge. Use edge computing to preprocess data on-site.

Q: Is data securely erased?

Yes. After device return, AWS completely erases data according to NIST 800-88 standards. Devices are reused.

Q: Can I use multiple devices simultaneously?

Yes. Use multiple Snowball Edge devices in parallel to reduce migration time. Example: 5 devices = 5x faster transfer.

Q: Can I transfer directly to AWS services other than S3?

Snowball Edge primarily transfers data to S3. To move data from S3 to other services (EFS, FSx), use DataSync.
