b2share.eudat.eu · academic · storage/b2share · JSON · compare

Free tier	20 GB per record, 10 GB per file, and explicitly unlimited records and unlimited files. unit GB; metered on unstated
Price	none stated
Per-object cap	10 GB per file (10000000000 bytes)
Retention	not stated
Egress	Free, unmetered, direct per-file content URLs (GET /api/records/<id>/files/<name>/content). No egress terms or pricing exist; EUDAT is publicly funded.
Identity	institution (placeholder) inferred from the category 'academic'; the source record states no identity cost, so this is a class assumption, not evidence
Limits	per-object-cap 10 GB per file source write-gated review source 10 GB per file, 20 GB per record — so 20 TB needs ~1,024 records, which trips EUDAT's 'fair share' clause: 'the uploading of large number of files or creating large number of records is not considered fair use' and they ask you to contact them first. Live rate limit header: x-ratelimit-limit: 500, x-ratelimit-remaining: 499.
Binding	per-object-cap the per-object cap sets the shard size and therefore the object count; it bounds the total more tightly than any headline quota
Interface	rest, rclone rest
Tooling	InvenioRDM-style REST API (live: GET /api/records?size=1 -> 200 with hits/entries and per-file content links); OAI-PMH; DOI minting (10.23728). Python client via plain requests. No rclone backend.
Composes with	20 GB per record x unlimited records. 50 records = 1 TB; 1,000 records = 20 TB in one account. The docs state outright 'There is no limit to the number of files you can deposit or records you can create'.
Reliability	Rate-limited at 500 requests/window and watched for bulk growth; EUDAT says it 'will increase back-end storage capacity incrementally when necessary', which implies throttling rather than deletion, but the fair-share clause is the trigger for manual review.
Notes	20 GB per record, 10 GB per file, and explicitly unlimited records and unlimited files.
Evidence rung	reported One page read moves it to documented.
