Microsoft is moving towards possibilities to backup SaaS solutions running on azure.
One of the first that is supported in Azure Backup is Storage accounts. Or to be precise SMB fileshares running inside the storage accounts.
So when planning on using this feature take into account that it only fileshares not blobs, queues and tables.
Backup for blobs is most definitely also needed.
I’m still hoping for other options to be released soon.
Things like Office 365 backup (mail and sharepoint / onedrive ) is very needed.
