Where Amazon S3 fits
Application files with explicit access, retention and recovery requirements.
When to choose another approach
Durability differs from recovery after deletion or overwrite. Recovery depends on configuration.
Worked example and evidence
Fictional inspection team: upload a restricted report, allow its reviewer to download it and recover a prior version after an overwrite.
What you need to supply
File sizes/types, permissions, retention, recovery target and bucket configuration.
What acceptance should demonstrate
Unauthorized access fails. Demonstrate expiry and recovery of a deleted or overwritten sample.
Running costs and responsibilities
Budget versions, requests, transfer and backups. Assign retention and restore ownership.
Technical scope to confirm
Versioning retains object variants when enabled. Lifecycle and deletion policies determine what remains available.
A proposal should identify the systems and data, direction of sync, access feasibility, failure handling, named owners and included deliverables. Listing this technology does not imply a prebuilt connector, vendor partnership or included feature.
Can deleted or overwritten files be restored?
Only if the required version or backup still exists and the operator has access. Demonstrate the chosen recovery path.
