Internxt S3

Free cloud object storage

Cloud object storage is a storage architecture where each file is stored as a self-contained object (data, metadata, and a unique ID) in a flat namespace addressable over HTTP. It scales horizontally across distributed servers, which is why it suits backups, media libraries, analytics data lakes, and any workload measured in TB rather than GB.

The S3 protocol is the HTTP-based API set Amazon Web Services published for its Simple Storage Service, now the de facto standard for cloud object storage. Internxt is AWS S3 and IAM API compatible, so any client built for AWS S3 (aws-cli, boto3, rclone, MinIO, Cyberduck, Terraform's S3 module) works against Internxt by changing the endpoint.

Free cloud object storage usually means free up to a cap (free transfer, free operations, or a free trial period), not free forever. AWS S3 free tier covers 5 GB for 12 months. Internxt's version is different: free data transfer, no API charges, and a 30-day money-back trial above a monthly storage floor.

Yes. Internxt is AWS S3 and IAM API compatible, so clients built against the standard S3 API set work without code changes. Common ones: aws-cli, boto3 / botocore, rclone (setup docs published by Internxt), MinIO clients, Cyberduck, s3cmd, FileZilla Pro, Terraform's aws_s3_bucket resource. Swap the endpoint URL and access keys, and the calls themselves don't change.

1 TB minimum for 30 days. Every object you store counts against a 30-day retention window, so if you delete a file before day 30, you're still billed for the remaining days. AWS S3 Standard-IA and One Zone-IA carry the same 30-day minimum-duration rule, and Glacier carries 90. It keeps storage pricing predictable for both sides.

Yes. The monthly minimum is €7, which covers 1 TB of storage. Storing less than 1 TB still bills at the 1 TB rate, and there's no proration below the floor. Above 1 TB, the rate stays €7 per TB per month, billed monthly. The €7 number is what shows up on every invoice unless you exceed the floor.

Objects smaller than 4 KB are billed as 4 KB. If you upload a 500-byte log line as its own object, the storage line counts it at 4 KB. AWS S3 Standard-IA and Glacier classes use the same minimum-object-size pattern at higher thresholds (128 KB on Standard-IA). The fix, when it matters, is to batch small objects into larger files before upload.

Overwriting without versioning moves the old object into the 30-day minimum-duration bucket. If you upload file.pdf today and replace it tomorrow, you're billed for one day of active storage on v1, 29 days of deleted-storage retention on v1, plus active storage on v2 from day two onward. Either version the bucket, or batch updates beyond the 30-day window.

Email Internxt support for help, refund requests inside the 30-day window, and cancellations. Live chat is available in-product. Cancellation is processed manually: you email, the team confirms, and the subscription stops at the next billing cycle. If you delete objects before day 30, the 30-day minimum-duration policy still bills the remaining days, so timing the cancel matters if your storage is fresh.
