Backup ReadyNas to ReadyNas with rsync and exclude lists

So editing it is no longer possible, at least not with RAIDiator 4.2.5. Interestingly /frontview/bin/backup is the only file in that folder compiled that way. What gives? That's interesting. I hope they haven't done that in the new 4.1.6, too, because that would prevent me from upgrading when I get back from holiday. Perhaps they did this to protect proprietary information, but I'm just guessing. It would be a step backwards if we can no longer hack that file.

I've just added a ReadyNAS Pro alongside my NV+ and can confirm that backup is now a byte-compiled file. Bummer.

The good news is that RAIDiator 4.2.8 (and maybe a couple of earlier revisions) adds built-in support for excluding directories from rsync back-ups. No more need to hack that in.

The bad news is that the new support isn't a generic solution, so there's still no way to add arbitrary options to the rsync command line. In particular, I still need --size-only.
