Data Archival Cost Calculator

About the Data Archival Cost Calculator

Archival storage is the cheapest tier for keeping data long-term, but the true cost goes beyond the per-GB storage rate. Retrieval fees vary dramatically by speed tier—expedited retrieval can cost 10–20× more than standard retrieval. A well-planned archive strategy balances low storage costs with acceptable retrieval expenses when data is eventually needed.

This calculator models the total cost of data archival by combining storage cost (archive volume × storage rate) with retrieval cost (retrieved volume × retrieval rate × speed tier multiplier). It supports multiple retrieval speed tiers—expedited (minutes), standard (hours), and bulk (12–48 hours)—so you can compare the cost of fast versus slow data restoration.

Use this calculator for budgeting compliance archives, disaster recovery cold storage, or media asset libraries where data is rarely accessed but must be preserved for years or decades.

When This Page Helps

Archive storage rates look cheap until retrieval fees arrive. This calculator reveals the true total cost of archiving and retrieving data, helping you pick the right speed tier and budget accurately for long-term data preservation.

How to Use the Inputs

1. Enter the total archive volume in GB.
2. Enter the monthly storage rate per GB.
3. Enter the expected monthly retrieval volume in GB.
4. Select the retrieval speed tier (expedited, standard, or bulk).
5. Enter the per-GB retrieval rate for the chosen tier.
6. Review the combined monthly storage and retrieval cost.

Example Calculation

Tips & Best Practices

• AWS Glacier Deep Archive offers the lowest storage rate at ~$0.00099/GB/month.
• Expedited retrieval from Glacier costs ~$0.03/GB; bulk is ~$0.0025/GB.
• Azure Archive Blob requires rehydration before access—plan for 1–15 hour delays.
• Consider data compression before archiving to reduce both storage and retrieval volume.
• Set minimum storage duration charges—Glacier has 90–180 day minimums depending on the tier.
• Test your restore process annually to ensure archived data is actually recoverable.

Cloud Archive Pricing Comparison

AWS Glacier Deep Archive: ~$0.00099/GB/month storage, $0.01–$0.03/GB retrieval. Azure Archive: ~$0.002/GB/month storage, $0.02/GB rehydration. GCP Archive: ~$0.0012/GB/month storage, $0.05/GB retrieval. Compare total cost including expected retrieval patterns, not just storage rate.

Compliance Archive Requirements

HIPAA requires 6-year retention of medical records. SEC Rule 17a-4 requires financial records for 6–7 years. GDPR requires deletion when no longer necessary. Archive solutions must provide immutability (WORM) for compliance—enable Object Lock or legal hold features.

Disaster Recovery and Archives

Archives serve as a last line of defense in disaster recovery. Store archives in a different region than primary data. Test restore procedures quarterly. Document the retrieval process so it can be executed under stress during an actual disaster.

Frequently Asked Questions

• What are the retrieval speed tiers?

  Expedited delivers data in 1–5 minutes at the highest per-GB cost. Standard retrieval takes 3‒5 hours at moderate cost. Bulk retrieval completes in 5–12 hours at the lowest cost. Choose based on your recovery time objective (RTO).

• Is there a minimum storage duration for archives?

  Yes. AWS Glacier has a 90-day minimum; Glacier Deep Archive has 180 days. Azure Archive has 180 days. Deleting data before the minimum incurs early deletion charges equal to the remaining retention cost.

• How does archive compare to tape storage?

  Cloud archive eliminates tape management hardware and media degradation risks. Tape can be cheaper at petabyte scale for truly offline storage. Cloud archive wins on retrieval speed, geographic redundancy, and operational simplicity.

• Should I encrypt archived data?

  Always encrypt archives. Server-side encryption (SSE-S3, SSE-KMS) adds negligible cost and is often enabled by default. Client-side encryption provides stronger protection but adds key management complexity. Both are recommended for compliance.

• Can I reduce retrieval costs?

  Yes. Retrieve only what you need—use S3 Select or Glacier Select to query specific columns or rows within archived files. Batch multiple small requests into fewer large ones. Use bulk tier when time permits.

• What is the per-request charge for archive retrieval?

  Beyond per-GB fees, archive providers charge per retrieval request (e.g., $0.05 per 1,000 requests for Glacier). Retrieving many small files is more expensive per GB than retrieving fewer large files. Consider tarring files before archiving.
