The cheapest option depends on how often you need to access the files and whether you need fast restores.
Usually cheapest overall
Cold/archive storage is typically the lowest-cost file storage for old application files:
- AWS: S3 Glacier Deep Archive
- Azure: Blob Storage Archive tier
- Google Cloud: Archive Storage
This is best if the files are:
- rarely accessed
- mainly for compliance, backup, or long-term retention
- okay with slow retrieval times
If you may need occasional access
Use a low-cost object storage tier instead of true archive:
- AWS S3 Standard-Infrequent Access (IA)
- Azure Cool Blob
- Google Cloud Nearline
These cost more than archive, but retrieval is faster and usually cheaper to restore.
Important caveats
- Archive tiers often have retrieval fees
- Some have minimum storage duration charges
- If you access files often, archive can become more expensive than expected
Practical recommendation
For old application files:
- Long-term, rarely used: archive storage
- Occasional restore/testing: infrequent access / cool storage
- Need filesystem-style access: cheaper network file storage may be better than archive, but not the absolute cheapest
If you want, I can compare the cheapest options across AWS, Azure, and GCP for your file size and access pattern.
