Considerations and Limitations

Consider the following considerations and limitations.

General

Ensure that you have a backup of the workload that you plan to restore to Google Compute Engine.
Check if you need to configure a helper appliance for restore. For more information, see Helper Appliances. When possible, it is recommended to use restore without a helper appliance.
For recovery without a helper appliance, place the gateway server associated with the backup repository where the backup is stored or the backup server into the Google Compute Engine where you plan to recover workloads.
Verify that the backup server and repositories with workload backup files have access to the internet.

If backup files are located on deduplicating storage appliances or shared folder repositories, ensure that gateway servers communicating with these repositories have internet access.

If you plan to assign Google labels to the restored workload, check limitations for labels in the Google Cloud documentation.

User Account Permissions

Confirm that the IAM service account you plan to use for restoring workloads to Google Compute Engine has the necessary permissions. For more information, see Google Compute Engine IAM User Permissions.

Source Workload Considerations

If you restore workloads from backups of virtual or physical machines (non-Google Compute Engine virtual machines), review the supported operating systems and their differences from standard images in Google Cloud documentation.
Check that the logical sector size of disks you plan to restore is less than 4096 bytes. Disks with a logical sector size of 4096 bytes will be unreadable in Google Compute Engine.
If you use a cloud-init-based Linux distribution, use SSH keys for authentication. If you use a password, it is blocked after restore for security reasons. To reset the password on the restored VM, use technologies described in Google Cloud Documentation.

Helper Appliance

If you want to restore from backups in an on-premises object storage repository, the helper appliance machine must have access to the source object storage repository. To provide access to object storage repositories, you can use VPN or Google Dedicated Interconnect. For more information, see the Google Cloud documentation.
To upload one machine disk to Google Compute Engine, the helper appliance requires 1 GB RAM. Make sure that the type of Google Compute Engine instance selected for the helper appliance offers enough memory resources to upload all machine disks. Otherwise, the restore process may fail.

The VPC route table must contain a route from the IP address of the Veeam Backup & Replication server to an active Google Cloud internet gateway. For more information on internet gateways and how to create route tables, see the Google Cloud documentation.
Check that OS Login is disabled for the project where you plan to recover VM instances. For more information on how to configure OS Login, see the Google Cloud documentation. If you want to have OS Login enabled, use restore without the helper appliance.
