If you have a number of VMs running interdependent applications, you need to fail over them one by one, as a group. To do this automatically, you can prepare a cloud failover plan.
Before creating a cloud failover plan, ensure VMs that you plan to include in the failover plan have successfully replicated at least once. Then use the Cloud Failover Plan wizard to create a cloud failover plan.
To launch the Cloud Failover Plan wizard, do one of the following:
- On the Home tab, click Failover Plan and select Cloud Connect (vSphere) or Cloud Connect (Hyper-V).
- Open the Home view, click the Replicas node in the inventory pane, right-click the Failover Plans node and click Failover Plan > Cloud Connect (vSphere) or Cloud Connect (Hyper-V). This option is available if you have already configured at least one failover plan.
- Open the Home view, click the Replicas node in the inventory pane, select one or several VMs in the working area, click Add to failover plan > New Cloud Failover Plan on the ribbon or right-click one or several VMs in the working area and select Add to failover plan > New Cloud Failover Plan. In this case, the selected VMs will be automatically included into the failover plan. You can add other VMs to the failover plan when passing through the wizard steps.
At the Failover Plan step of the wizard, specify a name and description for the failover plan.
- In the Name field, enter a name for the failover plan.
- In the Description field, provide a description for future reference. The default description contains information about the user who created a failover plan, date and time when the plan was created.
At the Virtual Machines step of the wizard, select VMs that you want to add to the cloud failover plan. You can add separate VMs from the list of VMs that are added to the replication jobs targeted at the cloud host.
To add VMs:
- Click Add VM.
- Browse existing replication jobs targeted at the cloud host and select all VMs or specific VMs from replication jobs: To quickly find VMs, you can use the search field at the bottom of the Select Replica window. Enter a VM name or a part of it in the search field and click Start search or press [ENTER].
At the Default Gateways step of the wizard, check and, if necessary, specify default gateways in every IP network in the production site that are used by VMs added to the cloud failover plan. The network extension appliance on the cloud host will use network settings of specified gateways to route traffic between VM replica networks and external networks after full site failover.
Veeam Backup & Replication automatically specifies default gateways in detected production networks during the first run of the replication job targeted at the cloud host. If, for some reason, the list of default gateways at the Default Gateways step of the wizard is empty, you should specify default gateways manually.
To specify default gateways, click Manage default gateways at the bottom of the Cloud Failover Plan wizard window. Then use the Default Gateways window to specify default gateway settings.
At the Public IP Addresses step of the wizard, specify IP addressing settings for VM replicas. You can create one or several public IP addressing rules to make a VM replica accessible over the internet by a public IP address that OneNet has provided to you through the hardware plan.
When your production VM fails over to its replica during full site failover, Veeam Backup & Replication assigns the public IP address that is specified in the rule to the network extension appliance on the cloud host. The network extension appliance redirects traffic from this public IP address to the IP address of a VM replica in the internal VM replica network. As a result, a VM replica for which you have created the public IP addressing rule can be accessed over the internet like a production VM without interrupting the production site operation.
To create a public IP address mapping rule:
- Select the Assign public IP addresses to use during full site failover option and click Add to open the Public IP Address Mapping Rule dialog window.
- In the Replica VM field, click Add VM and select a VM replica that you want to make accessible over the internet.
- In the Public IP address field, select a public IP address from the list of public IPs supplied to you by OneNet. In the Port field, specify the number of the port on the OneNet network extension appliance from which Veeam Backup & Replication will redirect traffic to the VM replica that must be accessible over the internet.
You cannot specify port 22 as a port for the public IP address that is assigned to the network extension appliance. Veeam Backup & Replication uses this port for communication with the network extension appliance.
- In the Internal IP address of replica VM field, select the IP address of the VM replica in the internal network. In the Port field, specify the number of the network port on the VM replica to which Veeam Backup & Replication will redirect traffic from the network extension appliance. For Linux-based VM replicas, you must specify the internal IP address manually, because Veeam Backup & Replication cannot detect an IP address of a Linux-based VM in the tenant's production network.
- In the Description field, provide a description for future reference.
- Click OK.
At the Summary step of the wizard, complete the procedure of a cloud failover plan creation.
- Review the configuration information on the created cloud failover plan.
- Click Finish to exit the wizard.
