I'm currently running VBR Community Edition to back up 5 Hyper-V VMs, 2 hypervisors (volume backup) and replication of the Veeam Server (which is a VM on one of the hosts) to the other host. This is all being backed up to an on-premises NAS via an iSCSI target.
This is all working great, save for one issue where I rebooted the NAS and the volume that was previously formatted as ReFS came back as RAW and couldn't be recovered, which lost me 20 days of backups, so I ended up having to start from scratch (this time I formatted as NTFS, for what it's worth).
That prompted me to look more closely at cloud backups. Having started a trial of a S3 solution I was unable to get it to work (couldn't see the bucket) in Veeam, but upon further checking it seems like backing up to object storage is not supported in Veeam Community Edition anyway.
It looks like I would need to buy Veeam Data Platform Essentials to do this. It seems like a reasonable price when I look at this page:

..but upon proceeding further it seems like you can only buy these in packs of 5, making the minimum purchase £446.23/year. With my setup, would I not need at least 7 licences? (5 VMs + 2 hypervisor backups)
So I'm just trying to understand if I'm looking at either continuing to use VBR Community Edition and no cloud backups for free, or have to pay a minimum of £446.23/year to get access to S3/cloud backups? Is that right?
Thanks in advance!
