remove needless TODO
This check isn't actually warranted, because this function never receives "untrusted" input: we always call it directly on the filepath of a siafile.
In fact, we should probably change the modules.Renter
interface so that CreateBackup
/UploadBackup
are a single function. (I think we need to retain CreateBackup
/LoadBackup
for compatibility reasons, though.)
