-====== C14 - Frequently Asked Questions ====== 
  
-<note warning>C14 Classic has reached its end of life and is no longer available. We recommend to use [[https://www.scaleway.com/en/c14-cold-storage/|C14 Cold Storage]], our S3 compatible data archiving solution.</note> 
- 
-=== 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 [[en:account-management:account:billing|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. \\
