Before You Begin

Before you restore workloads to Amazon EC2, consider the following requirements and limitations:

  • Check whether a helper appliance must be configured for restore. For more information, see Helper Appliances.
  • Make sure that a user whose credentials you plan to use to connect to AWS has permissions to restore to Amazon EC2. For more information, see AWS IAM User Permissions.
  • You must have a backup of the workload that you plan to restore to Amazon EC2.
  • The backup server and repositories with workload backup files must have access to the internet.

If backup files are located on deduplicating storage appliances or shared folder repositories, the internet connection is required for gateway servers that communicate with these repositories.

  • If you use a cloud-init-based Linux distribution, we recommend that you use SSH keys on these distributions. If you use a password, it is blocked after restore for security reasons. To reset the password on the restored instance, use the technologies described in AWS Documentation.
  • If you restore workloads other than EC2 instances, check the supported OS, EC2 instance and file system types in the AWS Documentation.
  • Check that the logical sector size of disks that you plan to restore is less than 4096 bytes. Contents of disks whose logical sector size is 4096 bytes will be unreadable in Amazon EC2.
  • [For restore of EC2 instances without helper appliance] If you restore workloads with more than five disks, check that the Limit maximum concurrent tasks option of the repository where the backups are stored is equal or less than the limit of the AWS ImportVolume service for concurrent tasks. Veeam Backup & Replication uses this service during the restore. For more information on the limit, see AWS Documentation.
  • If you plan to assign AWS tags to the restored EC2 instance, check limitations for tags in the AWS Documentation.
