Disaster recovery testing scenarios =================================== `Disaster Recovery `_ (DR) is the ability of software and/or services to handle extreme scenarios; this could be the failure of the software itself or an outage within a datacenter. These situations are uncommon but can have a huge impact, so they need to be prepared for. Aiven provides this service to any Enterprise Support customers and can run these scenarios at your request up to 4 times per year. What is a Disaster Recovery scenario? ----------------------------------------------------------- This is a preset scenario where an Aiven specialist will simulate an issue with your service and ``sabotage`` one (or more) of your Virtual Machines. For example, with an Aiven for PostgreSQL® service, we can ``sabotage`` the Primary instance and test the failover functionality or we can sabotage both nodes to test recovery time for a complete outage. What is needed? ----------------------------------------------------------- 1. At least 7 working days notice and the time (plus timezone) that you would like this carried out. 2. A ``throwaway`` service (i.e. one that is created specifically for this scenario and not a service used in Production). 3. The virtual machine and/or the availability zone that you would like to target. 4. An Enterprise Support contract. How do we request this? ----------------------------------------------------------- You can request this by opening a support ticket, emailing `support@Aiven.io `_ or by contacting your Customer Success Manager. How is it run? ----------------------------------------------------------- * All communication during the exercise will occur in the support ticket. * We will contact you to confirm the start of the scenario, the actions we will take and the service affected. The scenario will not begin until it is confirmed by you. * Actions taken on the service and/or virtual machines will be communicated through the support ticket.
