Why cannot I add a VM or Yandex BareMetal server to Cloud Backup?
Make sure that:
- The VM is created from a supported image or (if the Cloud Backup agent is installed manually ) Cloud Backup supports the VM's operating system.
- Service account linked to the VM has the
backup.editorrole. - Security group is correctly configured for the VM.
For more information, see Connecting Compute Cloud VM instances to Cloud Backup.
- The server runs a supported operating system.
- The service account whose IAM token is used to install the Cloud Backup agent has the
backup.editorrole. - The server has a public IP address assigned.

I get an error when trying to restore a VM or BareMetal server from a backup
Error message:
Not all of the items are mapped. Please, check your goal instance and its volumes.
The error occurs because Cloud Backup cannot find a suitably sized disk on the target VM.
The boot disk of the target VM or BareMetal server must be at least the size of that of the source VM.
Check the target VM disks and increase their size as needed. You can also use another VM or BareMetal server with suitable parameters.
Note
To avoid errors when recovering from a backup, start by comparing the parameters of the disks and partitions of the backup against those of the VM or Yandex BareMetal server. For more information, see Viewing the parameters of disks and partitions in a backup.

Make sure that:

- Service account linked to the VM has the
backup.editorrole. - Network access for your VM is enabled.
