Automated VM Failover
Recover from a disaster by running a single job
A Path to Successful Recovery
While disasters can sometimes be predicted (such as when you receive a weather warning or a power outage notification), most often, they strike out of the blue. Disaster impact can be mitigated by planning and preparing in advance. This is where VM replication and failover features can help.
The VM replication feature allows you to create and maintain identical copies of your VMs in a target location. Once you have a standby copy of your production VMs at a DR site, you can create VM Failover jobs to simplify and automate the disaster recovery process.
With a VM Failover job, you can specify which VM replicas should be powered on and create rules for reconfiguring VM networking (since the network configuration at the DR location is likely to be different from that of the source site).
How Automated VM Failover Works
To begin with, you need to set up VM replication. You can choose to replicate all your VMs with one VM Replication job or create multiple jobs for different groups of VMs, setting appropriate schedules and options for each job. Once you are done, you can create a single VM Failover job and link multiple VM Replication jobs to that VM failover job. This allows you to perform disaster recovery with a single click.
In this scenario, all new VMs added to VM Replication jobs get automatically included in the VM Failover job as well. There is no need to manually update your jobs.
To further automate disaster recovery, you can create network mapping rules. For example, a network mapping rule can switch VM replicas from network A to network B upon failover. Moreover, you can create VM re-IP rules. For example, a re-IP rule can change the IP address of VM replicas from 192.168.77.XX to 10.30.30.XX upon failover.
If you perform a planned failover or a datacenter migration, you can choose to power off the source VMs at the primary site, ensuring they do not interfere with the VM replicas when they come online.
VM Failover jobs make the disaster recovery process simple and easy – once they are created, you can focus on protecting your infrastructure. Failover jobs can be automatically populated with VMs from the associated Replication jobs, apply your pre-configured networking rules to new VMs, and remain ready for execution at any time.
