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 plan to restore a Linux- or Unix-based workload, check that Amazon EC2 supports the kernel version. If the version is not supported, consider changing the kernel version before backing up. For more information on kernel versions, see AWS Documentation.
• If you plan to 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 equals 512 bytes. Contents of disks whose sector size is 4096 bytes will be unreadable in Amazon EC2.

• Veeam Backup & Replication does not support restoring disks encrypted by BitLocker, except for restoring from backups created by Veeam Agent for Microsoft Windows. For more information, see the Veeam Agent for Microsoft Windows User Guide.

• [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.
• [For Veeam Backup & Replication server located in Amazon EC2] If you restore workloads from a backup stored in an object storage repository, we recommend using Private IPs to increase the transfer speed. For more information, see this Veeam KB article.
