In the off chance that Bonsai (and much of the internet with it) experiences an entire loss of an AWS EC2 region, all of your cluster’s data is maintained in AWS’s S3 system, which has a reliability guarantee of 99.99% uptime and 99.999999999% durability.
If such a failure happens, Bonsai’s staff will work with your team to understand where you will be relocating your application and can then initiate a restore process into a cluster in the same AWS Region while maintaining your existing DNS connections. Alternatively, clusters on an Enterprise plan have the option to re-provision to a nearby AWS Region.
An event like this is handled as a Severity 1 incident.
How much time will it take to restore?
There are several factors to calculate the time to restore: lead time for a support request or Bonsai’s internal alerting system to our Platform team, plus primary data restoration time from the AWS S3 system.For example, recovering 1 TB of primary data at 1,000 MB/second would take just over two hours. Performance may vary. With 5 TB of primary data, that can approximately take over 10 hours to restore.
