Yes, you're absolutely right. Backup tools may attempt to backup the 
.journal, which is fine, because it's safely readable, and usually not large 
enough to take up significant space on the backup media. And then on restore, 
the backup tool would hit hard against .journal's immutable flag, and 
probably end up complaining loudly and skipping the file. Seems harmless 
enough. Of course, tools such as tar accept a list of files to exclude, if 
you're worried about the space wastage.
