Hi there Piotr Kwaśniewski
Thanks for using QandA platform
Azure Backup doesn’t support AWS EC2 or EBS volumes natively. MARS/MABS are only supported on on-prem Windows servers or Azure VMs — you could install MABS/MARS on a Windows EC2 instance and back up files/folders to Azure, but that’s not an officially supported path for full VM-level backup or recovery, and it won’t protect EC2 like a native VM backup. Azure Backup also doesn’t support Amazon EBS snapshots or treating AWS VMs as first-class workloads.
For DR, Azure Site Recovery no longer supports replication from AWS to Azure — that capability was retired. So for AWS workloads, you'd need AWS-native backup/DR or a third-party cross-cloud tool.
If this helps kindly accept the answer thanks much.
