Azure Backups on Centos using Azure Agent RRS feed

  • Question

  • Hi mates.

    I have an interesting configuration.

    So, we have several VMs and configured proxy to communicate with the world.

    Currently, we have an issue with the fact that proxy is going down when backups are going started.

    Due to these facts, I have decided to create additional network interfaces to communicate with azure directly.

    But, I have faced the issue that backups still using eth0 instead of eth1 despite the added route.

    I checked several articles but did not find the proper information about networks and subnets which should be added to the route.

    Maybe I missed something.

    Could you please help me with correct rules in the Azure portal which should be added for the 2nd network interface to allow direct connection to the Azure portal.

    And also it will be great if someone could help me with routes in Centos which should be added to set up the connection using eth1.

    I used tcpdump -i eth0 port 443

    And found that system using these IP addresses when backups are running:

    However, I'm not sure how many addresses I should add else.

  • Correct me If am wrong. You're trying to backup Azure centos VM using MARS agent. If this is your scenario, I'm afraid to say it is currently not supported. Because MARS agent can only be installed on Windows machines. 
    Refer to support matrix link -

  • Hello,

    I have successfully installed waagent and seems that it is working correctly.I have used the following article:


    It has a proxy settings, but I'm trying to configure it to use direct connection to the azure to make backups.

    So, that cos I'm asking about correct configuration of firewall rules on the azure side and then how to properly configure routes to the azure.

    We have discussed internally how to make it and the possible solution is to create a separate vm and deploy another proxy on it.

    Create rules for this vm for direct connections to the azure and then forward VM's to use this proxy to connect to the azure.

  • What is the backup service you're using to backup your on premise VMs to Azure?

    Are these VMs on VMware or Hyper-V?
