  When you use Instant Restore for the first time and the to-be-restored disk has been backed up before the feature is enabled, you need to perform a full backup on the disk on the console or directly call the API for creating a full backup (POST /v2/{tenant_id}/cloudbackups). After doing this, the disk backups generated through APIs will support this feature.
