"""
Restore the backup BACKUP_DATESTRING of virtual machine DOMAIN stored in TARGET_PATH on the cluster primary coordinator. DOMAIN may be a UUID or name.
TARGET_PATH must be a valid absolute directory path on the cluster "primary" coordinator (see "pvc node list") allowing reads from the API daemon (normally running as "root"). The TARGET_PATH should be a large storage volume, ideally a remotely mounted filesystem (e.g. NFS, SSHFS, etc.) or non-Ceph-backed disk; PVC does not handle this path, that is up to the administrator to configure and manage.
The restore will import the VM configuration, metainfo, and the point-in-time snapshot of all attached RBD volumes. Incremental backups will be automatically handled.
A VM named DOMAIN must not exist; if the VM already exists, it must be removed before restoring. Renaming is not sufficient as the UUID will remain the same.
