At Veeam Console we cannot see last backup date. Next run or Last Result columns is great but some of VM's chained another jobs. So if chain breaked that VM jobs not started.
Yeah chained backups not recommended but this addition make it recommended i guess
Or maybe Last Result columns expand, it contains date too.
You can go to "Backups" and check all available restore points there.
By the way, Veeam ONE gives more options like "Unprotected VMs", "VMs backed up by several jobs" etc.
