I don't think you can, I beleive "file" is an invalid devclass.

Is anyone doing db backups to disk using devclass type FILE?

I know, it's not necessarily a good thing, but right now we have a db that
is large enough that the log can fill before a full db backup can run.

Before I set this up, I'm wondering if anyone else is doing this.
