Supported operating systems
Elastic Disaster Recovery allows replication of any physical, virtual or cloud-based source server to the AWS Cloud for a large variety of operating systems.
Windows notes
It is recommended to install all available Windows updates on the server.
Windows source servers need to have at least 2 GB of free disk space in order to launch a Drill or Recovery instance successfully.
When performing a recovery, you must boot the Failback Client with the same boot mode (BIOS or UEFI) as the Windows source server.
Linux notes
Elastic Disaster Recovery does not support 32 bit versions of Linux.
Ensure that you have Python installed on the source server (version 2.4+, version 3.0+) for Agent installation.
Only servers using the GRUB bootloader are supported.
Kernel versions earlier than 2.6.18-164 are not supported by AWS and Elastic Disaster Recovery. Therefore, servers that run these kernel versions cannot be replicated by Elastic Disaster Recovery.
Secure Boot is not supported in Linux.
When performing a recovery for a Linux server, you must boot the Failback Client with BIOS boot mode.

Elastic Disaster Recovery only supports x86 based operating systems.
