Part 10 – Recovery and Failback

The final stage of our process is to go ahead and perform a failover and failback of some virtual machines.  This should be performed using an unimportant virtual machine… please note that during the recovery and failback process, the source virtual machine will be powered off and therefore there will be a network outage to the virtual machine.

  • Once you have performed a test recovery, go back to the ‘Recovery Steps’ section of the SRM portal
  • Click on ‘Recovery’ at the top of the screen.  You will now see a screen similar to below:
    part10 - 1
  • As you can see the ‘Recovery’ option has a red alert sign to show that this will impact the usage on the virtual machines.  You must tick the box to say that you understand that this will permanently alter the virtual machines and infrastructure at both locations.
  • You then have to let the application understand whether this is a ‘Planned Migration’ or ‘Disaster Recovery’.  A planned migration will make sure that all of the latest changes are replicated to the destination location before cutting over, plus the task will cancel if there are errors encountered during the process… this option also requires the sites to be connected and storage replication to be functioning.
  • The ‘Disaster Recovery’ option will attempt to replicate the latest changes to the virtual machines but understands that the source site may not be available and therefore will use the latest replication data available to recover the virtual machines.  This will also continue the recovery even if errors are encountered.
  • In most cases we will probably be using the ‘Planned Migration’ method and therefore select this and then click ‘Next’
  • You will now receive a summary screen, click ‘Start’ to begin the planned migration
  • Switch back to the ‘Recovery Steps’ tab to check the progress… you can also have a ping test running to the virtual machine to see when the machine becomes available again.
  • You will also notice that the source virtual machine will be turned off and the destination virtual machine will be turned on.

  • You are now able to reverse the protection by clicking the ‘Reprotect’ button
  • The reprotect process will commit the results of the recovery and change the protection in reverse.
  • You will need to click the ‘I understand that this operation cannot be undone’ and then click the ‘Next’ button:

  • You will receive the summary screen once more and clicking the ‘Start’ button will confirm the reprotect.
  • Once the reprotect process is complete, you can once again perform a ‘Test’, ‘Planned Migration’ or ‘Disaster Recovery’ as performed earlier.

About the Author


I have been in IT for the past 15 years and using virtualisation technologies for around the past 8 years. I started, as quite a lot of people do, working with PCs after playing with such iconic systems like the ZX81, ZX Spectrum and then progressing through 386s, 486s, Pentiums etc. After being headhunted at sixth form to work for a small company based around Hertfordshire, UK. I began working with small businesses and gaining a lot of hardware experience. Three years later, after helping to increase the size of the business, I needed to gain exposure to a larger environment to progress my own career. I joined a large manufacturing company around Electronic Test and Measurement which progressed my skills onto more PC work, hardware work and then onto Server Operating Systems. I progressed again onto a consultancy company based in Reading, UK. Initially working as an engineer performing hardware / software installations for larger companies contracted out to the consultancy company, I moved up into a Consultant position continuing my travel across the UK assisting and providing solutions to companies. I finally moved on again to my current position, working back in Hertfordshire, UK. Again working for a large manufacturing company, this time with over 50,000 users worldwide. I am responsible for the datacenter hardware, the storage environment, the vmware environment and also implementing their new Citrix XenApp farm. My days are busy but also productive, its a friendly environment and in my four years of being with the company, I have seen many changes in technology and infrastructure in use within the company. About the site I started this site as I had been thinking of having more of a presence on the web for a while. On a daily basis, I perform tasks and use tools that others may not use or may not think to do and therefore I thought that I would share some of these experiences and tips with others to help with their day to day work. Currently, my main focus of work is around VMware and Veeam Backup & Replication but hopefully as my tasks progress, I’ll be able to share useful bits of information about other areas of IT as well.
