Upgrade Strategy Large Environment

We are now protecting 200TB worth of data for 400 VM's. We are dynamically provisioning storage, so it is a lot less in reality but when we upgraded to the latest Veeam B & R Edition last week it took 7 days for CBT to catch up running 24x7 since the backups had to evaluate each block of storage. As far as I can see Veeam scales well into Enterprise Environments with Proxies except for this scenario.

Is there a strategy I can use for Veeam upgrades to get around this? I can split the jobs up into multiple Backup Consoles and stagger the upgrades between backup consoles. But then I would have multiple places to manage backup jobs. What would be nice is if I can manually choose to only upgrade the agents on specific hosts and stagger the agent upgrades. I believe after the upgrade I was presented with a screen to upgrade all of the agents at once, and if I didn't then the host would show up with an error status in the backup console. I am also not sure if the new version of Backup console would be backward compatible with older agents.

Hi Collin,

We have forwarded your feedback on CBT driver improvements to our engineering team, so I would expect further development in this area in our next releases.

As to your idea of having multiple backup servers to address the upgrade/running full backup issue, then it seems like it would be a more complex solution in the long term compared to the upgrade of Veeam edition, which should not happen very often.

An ability to stage the upgrade procedure sounds like a good idea to me too.
