| Free tier | 30 GB per file with a 30 GB total per deposit and 1,000 files/folders per deposit; explicitly 'no cost to you'. Because deposits are unlimited and instant, the effective ceiling is per-deposit, not per-person. unit GB; metered on unstated |
|---|---|
| Price | none stated |
| Limits | Per-object-cap 30 GB/file; per-deposit 30 GB and 1,000 files; ZIP extraction capped at 1,000 entries. Content is scope-gated to social/behavioural/health sciences and replication data, and every deposit gets a DOI, so deposits are citable publications rather than scratch storage. |
| Identity | anonymous (inferred, not read) not published |
| Egress | Free, 'no cost dissemination to other data users'. Downloads are immediate and public in the format submitted; no egress pricing exists in the product. Restricted-use options exist but are optional. |
| Per-object cap | 30 GB per file (30000000000 bytes) |
| Retention | not stated |
| Interface | s3, rest, rclone rest |
| Tooling | Web upload plus 'Import From Zip' bulk extractor (1,000 files/folders per zip), versioning with a new DOI per version, and the underlying ICPSR deposit pipeline. No public rclone backend; automation is a scripted HTTP/form loop rather than a documented S3-style API — this is the weak point versus RepOD. |
| Composes with | Unlimited deposits x 30 GB each. 17 deposits = 510 GB; no account-level aggregate is published, and requests above 30 GB go to ICPSR Acquisitions for approval rather than being refused outright. |
| Reliability | Long-running (ICPSR since 1962) with DOI permanence and version history; the failure mode is editorial/scope rejection, not data loss or throttling. |
| Parsed numbers |
