Disclaimer I have not used s3 with bareos but done many cloud calculations.
Few things to think about using cloud. Are you running your SD in the cloud? Are your backup clients in the cloud? If not what’s your bandwidth? It will impact your backup and restore times significantly if you have modest WAN capacity for local clients servers. As for s3 pricing read this carefully https://aws.amazon.com/s3/pricing/ You have three components to pricing with s3 and I expect only two move the needle on cost. Data stored Bandwidth and retrieval Operations Opts rations are so cheap and guessing how bareos uses virtual tape volumes it’s prob not a big issue. Someone who has used it though can speak. Data stored its straight $/gb/month. So you need to estimate your total data stored for all your fulls and incrementals. Your right these costs decline when you look at glacier but there is a trade off. The cheaper to store the more expensive to access. Retrieval fees come in two forms. The first is bandwidth. Which fit most people is .09$/gb (unless your clients and servers are in the same aws region) for my cloud activities this is 50% of my monthly bill. It’s the thing that messes most cloud calculators for budget. That said if your sever is on prem you likely will never pay this if you don’t use always incremental or do any restores. So if your ok paying for restores maybe it’s ok. The cold tiers like glacier charge to access data. Again maybe fine if you almost never read it. Glacier runs $10/tb or more for transfer vs nothing for regular s3. With bandwidth your at ~$100/tb This is something to avoid deep archive. Their sla is many hours to get data. I don’t think deep archive is a backup replacement but a compliance archive replacement Also be aware glacier and deep archive have minimum retention times of 90 and 180 days. So you will always pay that at a minimum. Ok if your keeping fulls for a long time. Look at the auto tier options to manage aging volumes. So YMMV. If you are 100% in the cloud or you don’t use always incremental or have small data volumes or just a dr copy it works great. Personally I run my servers in aws and my full bareos setup on prem with a $400 tape library from eBay. This gives me diversity and most of the data in the cloud is small (websites email text) while the on prem is video photos and road warriors using always incremental.
