Using CV Backup/Restore Appliance in Azure to Protect Office365

Without the typos re-done below (sorry)

WE have CV 11 in our on-premises infrastructure as standard and are looking to extend into our Azure environment, which has been using Azure Backup to date 🤐

A business priority is protecting our MS-hosted Office 365 SAAS implementation and I would like to do this using an extension of our existing CV with the Marketplace B&R appliance usage.

I just need to know that their will be no lack of functionality in terms of what we can protect in Azure if we do it this way, instead of putting Metallic in, which my understanding is more for businesses who do not already have CV in-house..

Basically, we want to be able to protect all O365 components (email,sharepoint etc) in granular fashion, whether they be hosted by MS or ourselves, across our Azure subscriptions. Is this something we can do by going down the B&R appliance route to extend our current CV infrastructure?

I know metallic offers different pricing model, but would we lose O365, Kubernetes etc functionality if we go down B&R Appliance route rather than Metallic?

Thanks and regards
