Is anyone doing immutable backups to Amazon S3?

[HendersonD]

Right now we are doing 3 things using Veeam v10

1. We backup 40 VMs each evening from our production data center to our DR site which is across campus
2. We backup 40 VMs each evening from our production data center to an Exagrid box at our ISP which is 20 miles away
3. Every hour on the hour we replicate our 11 most important VMs from our production data center to our DR site

None of these will completely prevent a hacker from possibly destroying our backups and then dropping ransomware on our network. Our ISP charges us to have our older Exagrid box at their location. We are thinking about stopping the use of the Exagrid and instead contracting with Amazon to do Veeam immutable backups to their S3 service.

Is anyone doing immutable backups to Amazon S3? If so, is it working well?

We did not receive any concerns or bug reports in regards to the S3 immutability feature. So, based on the the accelerating Amazon consumption numbers, I'd say the this functionality looks solid and is quite popular. And we're hearing the same from compatible on-prem S3 storage vendor, too.

Are there specific questions regarding it that we can clarify? Or you are just after general perception?

Thanks!

BTW, you could simply try it with a test SOBR and a single VM before deciding.

And to add, not just do it with a test SOBR and single VM, but also keep the immutability flag low--just a day or two--so you can test the functionality but then still quickly delete the restore points after testing is complete.
