Cold Archive

Long term storage for infrequently accessed data


What is Cold Archive?

Cold Archive is a trusted & secure long-term storage offer to archive your increasing amount of “cold” data (for legal or business purposes) :

  • Compliancy with your specific legal constraints (Industry standards or sovereignty)
  • Cyber Protection against threats or ransomware infection chain
  • 3-2-1 backup best practice with different types of storage media, off-site location and offline copies

What type of data can I archive ?

  • Storage of the 3rd data set in a resilience plan
  • Data storage for legal reasons
  • Storage of scientific, geospatial, radiology data
  • Media storage


Global architecture

The solution offers a class of service specifically designed for archive. The architecture is extremely redundant and resilient. We thus guarantee the availability of your archive in the unlikely event of an accident or disaster in one datacenter and simultaneously the lost of a tape in a second datacenter. The data is replicated with erasure coding over 4 datacenters 100km apart.

    The service offers : 

    • A S3 endpoint to create a bucket and upload data on the bucket through S3 standard API
    • S3 API set  to manage the data : archive, restore, delete (and more)

    Once archived, data and metadata can not be changed. Metadata remains available in the active bucket for listing.

    Global Architecture

    The design is made of

    • object storage standard class to receive and restore data
    • librairies of tapes to archive the data. This long-term storage solution leverage the IBM Enterprise 3592 Tape technology and will be orchestrated by Atempo's software, Miria.

      During Alpha test, all interfaces are available for testing and evaluation (unitary and functional test). Data is not stored in Tapes. The Api structure can change during alpha test period according customer's feedbacks and needs.

      The time for the data retrieval to be available depends on the volume of data. For example, for a retrieval of several hundred TB, the average time is 48 hours. For a volume of a few TB, it can be between a few minutes and a few hours
