Are you sure? What makes you think that? I believe that File::RsyncP  
only implements the parts of rsync that are actually used by BackupPC.  
It only makes sense to support protocol >28 in File::RsyncP when  
features in BackupPC will use functionality only available with  
protocol >28.

What do you mean by saying that "long and/or weird file names don't  
exist in Linux"? Can file names be longer when using Windows than they  
can when using Linux? Can Windows file names be weirder? (If so, what  
does that mean exactly?)

I'm not saying that it's not true that protocol 30 did not add  
functionality that somehow fixes your problem (because I'm not really  
up to speed on what the protocol differences are), but I just have  
this gut feeling that the protocol version is not the problem. Craig  
might be able to explain all of this better.
