Backup infrastructures: some news from the field!

Posted by brain in Cloud on 27 avril 2025 with No Comments

Following the deployment of the new ScalarCloud production infrastructures, now distributed across 4 datacenters in Europe (and 2 in the USA), it’s now the backup infrastructures’ turn to evolve.
 
Objective: extend the distributed security model already applied to production to our backup infrastructures.
 
Concretely, instead of having one datacenter dedicated to backups and others to production, we now have a backup infrastructure distributed across 4 different datacenters.
 
To ensure the best possible response time between each production site and its backup, we conducted several rounds of latency measurements. The result:
 
– Gravelines will be backed up on Roubaix
– Roubaix will be backed up on Gravelines
– Limburg will be backed up on Strasbourg
– Strasbourg will be backed up on Limburg
 
Finally, SBG remains the current spare site for production, while Limburg now becomes the spare site for backup infrastructures.
