its been such a long time since I posted/participated in Veeam Forums, that doesn't mean I don't use Veeam on a daily basis or I don't interact with it..

For all the past years, we have been busy building knowledge, experience and maintaining On-Premise infrastructure. Its such a time to stop and change the focus/direction to the Cloud Option. In my opinion, I would start of exploring how our backup can be offloaded to the cloud and what are the benefitts over storing backups On-Premise.
Currently, I'm backing up nearly 40 TB of Data to Disk and from Disk, export to Tapes. My Total SAN Capacity almost 32 TB, divided into two iSCSI SANs, EMC VNXe3150 and IBM DS3512. Can someone help in estimating the cost of offloading 30 TB backups from On-Premise to the Cloud?
Is this price can be compared between the cost of the current iSCSI SANs to the Cloud..? Such as, If I'm renewing the support my SAN repository for 1 year nearly USD $9,840.43, is in the cloud could be better beside the Backup-DR-Protection ?
Which is better AWS or Azure when it comes to backup / pricing / connectivity...?
Do I require a Direct-Connect / Express Route in order to maintain a specific RTO for my backups restoration...?
I would highly appreciate if someone could highlights some of the good/bad things from real life experience as in these type of scenarios mostly the technical decision is the winner and the driver for such projects over some business decisions.
