Description:
Challenge
A Replication job targeting Cloud Hosts completes with the following warning: One or more source networks were possibly mapped onto the same cloud network. Simultaneous partial failovers of VMs residing on those networks may result in issues.
Cause
This warning is displayed when the software detects that the VM being replicated has more network adapters than the number of Network Extension Appliances that have been configured. From the Veeam Cloud Connect User Guide: On the tenant side, a separate network extension appliance must be deployed for every production IP network. For example, if there are 2 networks on the tenant production site, the tenant should configure 2 network extension appliances. The network adapter of each network extension appliance on the tenant side gets an IP address from the production network for which this appliance is configured. Related user guide pages are listed in the More Information section of this KB article.
Solution
Key Points If the tenant creates replicas of Windows-based VMs and the number of production networks equals the number of virtual networks on the cloud host, the tenant does not need to specify network mapping settings. In such a scenario, Veeam Backup & Replication automatically maps the production and virtual networks. Specifying network mapping settings may be required in the following cases: If the cloud host has fewer networks than the number of networks in the production infrastructure. If non-Windows VMs are included in the replication job. Automatic network mapping for non-Windows VMs is not currently supported in Veeam Cloud Connect Replication. If IPv6 communication is enabled in the Veeam Cloud Connect infrastructure.
