Step 3. Specify Restore Settings
At the Restore Settings step of the wizard, choose whether you want to restore files and folders to the original location, and to deploy worker instances in the production account.
Configuring Restore To Original Location
[This option applies only if you choose not to deploy worker instances in the production account]
To be able to restore files and folders to the original EC2 instance, set the Additional restore mode toggle to On.
To perform the restore operation, Veeam Backup for AWS will use the IAM role attached to the source instance. That is why before enabling the additional restore mode, assign all the required permissions to the IAM role. For more information on the required permissions, see Before You Begin.
Consider the following limitations:
To restore files and folders to the source EC2 instance, Veeam Backup for AWS uses Amazon Kinesis Data Streams. Kinesis Data Streams are charged on a per-shard basis. By default, Veeam Backup for AWS uses streams that are composed of 1 shard with a fixed data transfer rate of 1 MB per second. However, you can change the number of shards in the streams by moving the Restore rate slider. For more information on Kinesis Data Streams, see AWS Documentation.
If you plan to restore files and folders of the selected EC2 instance to the original location frequently, you can select the Keep the restore tool at the target instance check box. In this case, Veeam Backup for AWS will not remove the Veeam restore tool from the EC2 instance after the restore session completes, which will reduce the duration of future recovery operations.
Enabling Worker Deployment in Production Account
[This option applies only if you have selected a restore point of the Snapshot, Replica or Manual Snapshot type at the Restore Point step of the wizard]
By default, Veeam Backup for AWS launches worker instances used to perform restore operations in the backup account. However, you can instruct Veeam Backup for AWS to launch worker instances in a production account — that is, an account in which the snapshot that is used to restore files and folders of the source EC2 instance resides. To do that, set the Deploy workers in production account toggle to On, and specify an IAM role that will be used to launch worker instances, and further attached to these instances and used by Veeam Backup for AWS to communicate with them. The role must be assigned permissions listed in section FLR Worker IAM Role Permissions.
For an IAM role to be displayed in the IAM role list, it must belong to the AWS account in which the snapshot resides, and must be added to Veeam Backup for AWS as described in section Adding IAM Roles. If you have not added the necessary IAM role to Veeam Backup for AWS beforehand, you can do it without closing the Add Policy wizard. To add an IAM role, click Add and complete the Add IAM Role wizard.
It is recommended that you check whether the selected IAM role has all the required permissions to perform the operation. If the IAM role permissions are insufficient, the restore operation will fail to complete successfully. To run the IAM role permission check, click Check Permissions and follow the instructions provided in section Checking IAM Role Permissions.
