What should I use if I need file storage with lifecycle policies and low archival cost?

If you need file storage with lifecycle policies and low archival cost, the best fit is usually:
Amazon S3 + S3 Lifecycle Policies
- Store files in S3 standard
- Use lifecycle rules to automatically move data to cheaper tiers:
- S3 Standard-IA for infrequently accessed data
- S3 Glacier Instant Retrieval, Flexible Retrieval, or Deep Archive for long-term archival
- This gives you:
- object/file storage
- automated tiering
- very low archival storage cost
If you specifically need a traditional file system:
- Amazon EFS has lifecycle management to IA, but archival cost is not as low as S3 Glacier.
- So for archival-heavy use cases, S3 is usually better.
Rule of thumb
- Need “files” + cheap archive + lifecycle → Amazon S3
- Need mounted file system → Amazon EFS
If you want, I can also compare S3 vs EFS vs FSx for your exact workload.
