For organisations wanting to ultilse a VTL setup for Veeam instead of Veeam Cloud connect , they should be aware that VTL won't be able to roll up incremental backups into synthetic fulls, meaning every full back you are going to do will copy then entire full backup set to AWS.
AWS
Each virtual tape is limited to 30MB/s of upload throughput. To get up to the gateway maximum of 120MB/s, you need to have 4 virtual tapes running simultaneously

Gateway : Maximum of 95 GBP / Month
Archive Glacer Storage : 0.0034 GBP per GB / Month
Azure

You will need to pay for this VM in Azure : 133 GBP / Month
