A lot of resource usage.

If for some reason my main storage crashes I then have the option to connect that backup NFS storage to a secondary stand alone oVirt instance and run my VMs from there until the primary oVirt instance is repaired. What I want to avoid is implementing an older more inefficient solution that might work for a while but will eventually no longer work due to ovIrt updates in the future. <br></div><div><br></div><div>I know options like active-active failover and georeplication exist but that may be too complex for my needs although I would be interested in hearing about how some of you may be implementing these features. <br></div><div><br></div><div>In summary, I'd trying to figure out what the best backup option may be going forward with oVirt in the future so I can implement the best option from the start rather than having to change it all around in the near future. <br></div><div><br></div><div>Thanks!<br></div></div>
