Guideline for Planning vRealize Automation Backup

In my last post, I covered the steps  to Automat vRA distributed deployment using vRSLCM.In this post I will describe about  Guidelines for Planning  vRealize Automation Backups. 

vRealize Automation Preparations for Backup 

  A system administrator backs up the full vRealize Automation installation on a regular basis. Plan the backup around efficiencies and periods of low activity.

  You can use several strategies, singly or in combination, to back up vRealize Automation system components. For virtual machines (VMs), you can use the Snapshot function to create snapshot images of critical components or use native tools like Veritas NetBackup and vSphere Data Protection. If a system failure occurs, you can use these images to restore components to their state when the images were created. Alternatively, and for non-virtual machine components, you can create copies of critical configuration files for system components, which can be used to restore these components to a customer configured state following reinstallation

vRealize Automation complete backup includes the following components  

  • IaaS components  

  1. Proxy Agents  

  2. DEM Workers 

  3. DEM Orchestrator  

  4. Manager Services  

  5. Web sites 

  •    vRealize Automation appliance
  • PostgreSQL database. Applicable only for legacy installations that do not use an embedded appliance database  
  • Infrastructure MSSQL database

    (Optional) Software load balancers

    (Optional) Load balancers that support your distributed deployment. Consult the vendor documentation for your load balancer for information about backup considerations

    Guidelines for Planning Backups

    Use the following guidelines to plan backups:

    When you back up a complete system, back up all instances of the vRealize Automation appliance and databases as near simultaneously as possible, preferably within seconds. 

    Minimize the number of active transactions before you begin a backup. Schedule your regular backup to when your system is least active. 

    Back up all databases at the same time.  
    When you back up the vRealize Automation appliance and the IaaS components, disable in-memory snapshots and quiesced snapshots. 

    Create a backup of instances of the vRealize Automation appliance and the IaaS components when you update certificates.

    vRealize Automation Backup Order 

    You must back up the VMs for vRealize Automation components in a specific order. 

    When you use backup tools to schedule backups for your vRealize Automation deployment, you must back up the components in the following order: 

    If you have multiple components on a VM, select the order considering the latter component on the VM from the list. 

    If vRealize Orchestrator is a standalone component, then it should be backed up in no particular order before vRealize Automation components.

  2. Nice post. I learn something more challenging on different blogs everyday. It will always be stimulating to read content from other writers and practice a little something from their store. I?d prefer to use some with the content on my blog whether you don?t mind. Natually I?ll give you a link on your web blog. Thanks for sharing.
    There are certainly a lot of details like that to take into consideration. That is a great point to bring up. I offer the thoughts above as general inspiration but clearly there are questions like the one you bring up where the most important thing will be working in honest good faith. I don?t know if best practices have emerged around things like that, but I am sure that your job is clearly identified as a fair game. Both boys and girls feel the impact of just a moment?s pleasure, for the rest of their lives.
