You can put in an exclude file with a pattern to be ignored. I just dont 
want to speculate now without testing but you can try it out as 
explained here.

-z is only compression for transfer of files or the delta. So dont 
worry. Also, you might want to look at --delete and the related option. 
Based on what you want, you can delete files not in source, delete 
excluded files or certain patterns.

I never delete anything from my backup.



Getting there is only half as far as getting there and back.
