[rdiff-backup-users] case sensitivity

[Charlie Strauss]

When I backup from one macintosh HFS formatted machine to another HFS  
formatted machine the file names come with whacked names:

for example:

BBEdit.app

gets backed up with the name:

;066;066;069dit.app

Obviously it has something to do with case sensitivity.  But this  
makes things pretty much unreadable.  What causes this and how do I  
eliminate it?

I suspect the issue might be that there are two flavors of HFS one  
can use.  One is Case-Preserving Case-Insensitve HFS (the macintosh  
default) and the other is Case-Sensitive HFS (like ext3 or most linux  
fs).

For those that don't know the difference is this.  In case- 
insensitive HFS the file ReadMe and readme and README are the same  
file, buts it's name is preserved in the smae case as it was first  
created (and not reduced to say all uppercase or lower case).  The  
upshot is the README and readme cannot coexist in the same file. So  
untarring or copying from a linux system that has two files that  
differ only in case will cause one to be deleted.  If you use case- 
sensitive then it's just like most linux fs.

However, it seems like rdiff-backup could simply try to preserve the  
case when it can since normally this is not an issue and it's the  
rare exception where one has two files differing only by case.   
Indeed no such exception can exist  if one is copying FROM a Case- 
insensitve disk to a case-sensitive one.

So is this why this is happening and is there a setting that can fix  
this.  virutally all my liberal filenames are unreadable as it  
stands.  Is there a "no-mangle" flag?
