FAQ

Is Fil One S3-compatible?

Yes. Fil One provides an S3-compatible API. Any application, SDK, or tool that works with AWS S3 works with Fil One by changing the endpoint URL to your region's endpoint — https://eu-west-1.s3.filonecontent.com or https://us-east-1.s3.filonecontent.com. See the S3 Compatibility Reference for the full list of supported operations.

Do I need to know anything about blockchain or cryptocurrency?

No. Fil One is a standard cloud storage service. You sign up with an email, store data using familiar S3 tools, and pay with a credit card. The underlying storage infrastructure handles everything else transparently.

Where is my data stored?

You choose the region when you create a bucket. Fil One currently offers Europe (France) as eu-west-1 and US East (Michigan) as us-east-1. Objects in a bucket stay in that bucket's region, and the region cannot be changed afterwards, so pick it deliberately if data residency matters to you.

Within a region, storage is fulfilled by a distributed network of storage providers on Filecoin. All data is encrypted at rest. See Limits & Quotas for the region list and Encryption for how encryption is handled.

What happens when I delete an object?

On a bucket without versioning, the object disappears from your account immediately and there is no recycle bin or undo.

On a bucket with versioning enabled, a plain delete places a delete marker instead. The object stops appearing in listings, but every prior version is kept and can still be downloaded by version ID, and you can make the object visible again by deleting the delete marker. Those retained versions continue to count as stored storage. See Versioning.

Can I migrate from AWS S3?

Yes. Because Fil One is S3-compatible, you can use standard migration tools like aws s3 sync, rclone, or any S3-compatible transfer utility. Point the tool at your Fil One endpoint and credentials (with path-style addressing enabled — see SDKs & Tools). One naming caveat: Fil One does not allow dots in bucket names, so a bucket like my.data.bucket must be renamed during migration.

Do you charge for egress?

On a paid plan, no. There are no egress or data transfer fees.

The free trial is the exception: it includes 2 TB of egress rather than unlimited. See Trial & Billing.

What is included in the free trial?

The 30-day trial includes 1 TB of storage, 2 TB of egress bandwidth, and unlimited API operations. No credit card is required. See Trial and Billing for details.

Can I use Fil One for backups?

Fil One exposes an S3-compatible API, so backup software that targets S3 generally works — but check your tool's requirements first. We have not verified specific backup products, and three of the documented gaps are ones backup tools commonly depend on:

• No server-side copy in eu-west-1. CopyObject is confirmed in us-east-1 but not in eu-west-1; some tools use it for renames, moves, and deduplication.
• No CreateBucket over the API in eu-west-1. A tool that provisions its own repository bucket needs the bucket created in the dashboard first.
• No lifecycle rules. Retention-based pruning has to be handled by the tool itself.

Path-style addressing is also required, and bucket names cannot contain dots. Check your tool against the S3 Compatibility Reference before committing to it.

What durability guarantees do you offer?

Fil One is designed for high durability through distributed storage across multiple providers. Specific durability SLA details are available on request.

Can multiple users access the same account?

Currently, Fil One accounts are single-user. Each account has one login and one set of API keys. Multi-user organization accounts with role-based access are planned for a future release. In the meantime, you can create multiple API keys scoped to specific buckets and permissions to share limited access with other services or team members.

How does Filecoin protect the integrity of stored data?

Fil One is built on Filecoin, a distributed storage network where storage providers must continuously submit cryptographic proofs — called Proof of Replication (PoRep) and Proof of Spacetime (PoSt) — to prove they are still holding the data they committed to store. Providers that fail to produce valid proofs are penalised. This proof cycle runs at the network level and is not something you trigger or check yourself.

Fil One does not currently expose per-object proof data — content identifiers, deal IDs, and sealing state are not surfaced through the API or the dashboard, so you cannot independently audit an individual object today. For object-level integrity checks in your own application, compare the ETag returned by HeadObject against a checksum you keep, or apply Object Lock to make objects immutable for a fixed retention period.

What happens to my data if I delete it?

When you delete an object or bucket, it is immediately removed from your Fil One account and is no longer accessible via the API or dashboard. Because Filecoin stores data in sealed sectors, the underlying storage may persist for a bounded period until the sector naturally expires — an infrastructure detail set by the storage layer, not a user-facing state. That residual data stays encrypted, with key custody held by the regional storage operator rather than by you or Fil One (see Encryption). The data is inaccessible through Fil One from the moment of deletion.
