Not necessarily an error... but at least a note of such. Otherwise, the user will not know that the backup chain in question will remain in a folder forever that the user may not reuse. Those backup chains can be pretty large depending on usage scenario.
At least with a note the user can be prompted to do the chain deletion manually...
The other option is to offer the definition delete without the backup chain deletion option and describe in your documentation that a manual delete is required for the chain if the user wishes. This way the pop-up when deleting will always be the same.
