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):

  • 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

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.


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.

What is the data retrieval time?

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
