C14 - Frequently Asked Questions

What is C14?

C14 is designed to allow secure data storage in large volumes and for long-term data preservation, designed by the electronics laboratory of Online by Scaleway.
The TCO of our solution is far more economical than any entry-level hard drive on the market or tape storage, with a much higher level of security and reliability.


Which types of volumes of data can I store?

You can store an unlimited amount of data in the C14 cloud!
We provide an unlimited number of safe deposit boxes.
Each deposit-box can contain up to four billion files and grow up to 40 TB.


How does the safe deposit-box work?

The deposit-box is a free temporary disk space, provided to deposit your files.
Easily accessible within 7 days by Rsync, FTP, SFTP, and SCP, it provides up to 40 TB of storage.
After 7 days, or once you have copied your data into the deposit-box, your data will be stored reliably in C14.
Data recovery works in the same way. The deposit-box will be restored with the initial data.
We keep all attributes of your files (permissions, uid, gid, mtime, ctime, atime, …)


Why can I see the same archive several times?

When unpacking, you can choose to re-archive your temporary storage space automatically.
If you want to do that, you will end up with two archives:

  • The original archive
  • The new archive with any amendments

The purpose of C14 is to keep your data and to preserve its state. If you modify an existing archive, it creates a second archive, so that the first one always remains available (but erasable if needed).


What is an operation?

An operation is an action between the temporary deposit-box and the C14 infrastructure.
Archiving, Unarchiving, Destruction or verification.
Transactions are billed according to the volume of data to be processed.


Do I need to register a payment method to use C14?

Yes, you'll need to set up a Credit Card in your account to use C14.
Without it, you won't be able to use our service.
You'll find more information in our Billing section.


How many buckets can I create in one safe?

You can create up 8 buckets in one safe.


How much time takes each operation?

An archive operation is done depending on the load on the platform and the amount of data to archive.
This operation is variable and may take several days.
Unarchiving is done in priority, with an average duration of 2h, with a recovery speed of 650 MB/s.


How reliable is C14?

C14 is developed to provide a very high level of security and redundancy.
Our standard level of redundancy offers annual sustainability guaranteeing the loss of less than
1 megabyte per terabyte stored for ten years and only 500 kilobytes with enterprise-level.
We provide clear guarantees for compensation in case of data loss.


How is my data stored?

Each deposit-box is encrypted, replicated and distributed to a minimum of 10 to 44 independent peripheral devices.
Our storage algorithm allows the restoration of corrupted or lost data.
The infrastructure is hosted in Paris, in our unique anti-atomic bunker, built 25 meters deep between two thick
Parisian limestone benches, outside of any natural, technological or military hazard as known for today.


What is the security level?

We are using the AES-256-CBC algorithm by default, to encrypt all data in the deposit-box.
You are the only one that has the key for encryption. Our staff can't access your data.
