[X4U] Re: Using gnutar in Tiger.

[Robert Nicholson]

As far as I can tell it makes a big difference if you try to use -N  
with -X... whenever I use -N without using -X I do see an incremental  
backup but if I try to use exclusions with -N it always does a full  
backup instead of obeying the timestamp of the file I'm using.

Puzzled.
