Overview
Failover is a process of switching from the source VM in the production site to the CyberFortress disaster recovery site. How this occurs is determined by whether BaaS or DRaaS workloads are being utilized.
DRaaS Replication Failover
During failover, Veeam Backup & Replication recovers the VM replica to the required restore point and shifts all I/O processes from the source VM to its replica. As a result, you have a fully functional VM within a couple of seconds, and your users can access services and applications with minimum disruption. Failovers are broken down into two types: partial site and full site.
In partial site failover, the VMs being failed over are manually selected and powered on. Veeam Network Extension Appliances deployed in both the customer and CyberFortress environments connect and establish an L2 VPN tunnel to establish connectivity between failed over VMs and the production environment.
In full site failover, a pre-configured failover plan is executed. External IPs and ports can be pre-assigned, and failover VMs will boot in a pre-specified order. No VPN tunnel is established during full site failover, however there are several ways in which connectivity to these resources can be managed, such as a replicated VPN server or VMware Cloud Director users.
BaaS Failover
In BaaS failover, backup workloads are recovered into the recovery environment by a CyberFortress Disaster Recovery Specialist. This is a mostly manual process and takes longer than DRaaS failover.
