Limitations on restoring an Image-based backup to Amazon EC2
We use AWS VMimport service to import computer images to AWS Elastic Compute Cloud (EC2).
- First generation VMs are supported (MBR)
- Second generation VMs (UEFI/GPT) are not natively supported and should be converted with our tool.
- Server OS is supported when restoring to EC2, Desktop OS could be restored as AMI only. Read more
- Max number of volumes is more than 22.
- Disk size is limited to 2TiB. Check this article. Although it describes 1TB, the limit has been shifted since then.
- IPv6 is not supported.
Check here for other limitations.
- Ensure that your VM is compatible with EC2. Check here for details.
- Create VMimport role in your AWS account.
Changes applied to a machine that is being restored as EC2/AMI
- RDP is enabled.
- DHCP is enabled.
- Firewall is configured to bypass Remote Desktop Protocol (RDP) on port 3389.
Restore time heavily depends on the instance type (and especially temp instance size if such is used).
