Yes, there is a free tier and you can benefit from 75 GB of storage in C14 Cold Storage’s Glacier class for free with no time limit. In addition to 75 GB of storage and 75 GB of outgoing and inter-regional (AMS ↔ PAR) transfer in Object Storage’s standard class.

Nothing. Switching the object class from standard to Glacier is free.
Restoring objects from the Glacier storage class to standard storage class is also free of charges.

An object stored in the Glacier class is listed but cannot be downloaded instantly. It needs to be restored in standard class first.
This is the principle of C14 Cold Storage. Objects are stored on a not-always on cluster. The restoration of objects usually takes a few minutes.

It really depends on your type of Object Storage usage. If you consider that a 3-month old object is rarely used but still has a value, you might want to send it to Cold Storage’s Glacier class, for example.

Yes, this is possible, but currently limited to uploads via the API. When uploading a file from the Scaleway console, it is first upload to Object Storage’s standard class. Send it to Glacier once the upload has completed by changing the storage class of the object. To do so, click on Send to S3 Glacier in the drop-down menu of the object. Please note that by uploading your data on Object Storage’s standard class, you will pay the standard storage price until objects are sent to C14 Cold Storage’s Glacier class.

Our Paris underground databunker (DC4) provides an increased layer of security by being 25 meters deep below the surface in a bunker where the Glacier storage class cluster is available.
These storage clusters are available from any bucket in Paris or Amsterdam and all objects can change the storage class to Glacier.

The expiration and transition rules are evaluated every day at midnight UTC, but the actual action might take between one minute and twenty-four hours after evaluation.

Let’s first consider what they have in common: the two C14 services are hosted in DC4, a highly secure databunker located 25 meters underground in Paris.

Their differences are :

• Price: Scaleway Elements C14 Cold Storage has more advantageous pricing and integrates a free tier. You benefit from 75GB of free storage with no time limit.
• Protocols: C14 Cold Storage is 100% S3 compliant, whereas C14 Classic, available on Scaleway Dedibox, uses the FTP protocol.
• Encryption: C14 Cold Storage does not (yet) allow encryption.
• Recovery: with C14 Cold Storage, you can recover a data file with just a few clicks from the Scaleway console or via the API. C14 Classic requires the whole archive needs to be restored, even if you require only a single file from it.

C14 Cold Storage provides a data availability of 99.99 % and data durability of 99.999999999 %.

For increased security it is recommended to encrypt your data before sending them to C14 Cold Storage. Encryption should be done on the client-side to guarantee that there is no evidence of your private key stored on the cluster. Data can be encrypted using third-party solutions, like GPG. It is possible to automatize your backups and to encrypt them using a solution like Duplicity or Rclone using the crypt backend.

The GDPR requires that the life span of data be defined in two distinct cases:

• The deletion of data after a certain period of time
• The archiving of data that must legally be kept

Lifecycle management features meet both of these requirements by allowing you to set a timeframe beyond which your data are archived or deleted.

There is no maximum data size, C14 Cold Storage accepts an unlimited number of objects up to 5 TB each.
Large objects can be uploaded using multipart upload.

Firstly, C14 Cold Storage’s hard disk drive-based technology offers much better random data access time.
In fact, it takes only a few milliseconds to access your data, whereas access to a tape platform requires:

• A tape library to identify the cartridge on which the data is stored
• Reading several kilometers of tape to retrieve it

In addition, C14 Cold Storage enables parallel writing to multiple disks simultaneously, providing very high read and write speeds.
Redundancy is achieved by advanced parity mechanisms (6+3) on a large number of media, whereas tape technology does not allow this and is limited to CRC.
Finally, there is no risk of mechanical part failure (ex: robot) or wear and tear (tape drive).
