Sorry, I wrote those comments a bit late at night :)
I meant something like "the gigabyte barrier", as in "wow, my folder is now one 
gigabyte large !". This is not referring to any limit in the software or OS.
I was just thinking that more than one gigabyte was a bit large for only 
metadata, and is the reason why I had a look into the folder, and found the 
par2 files into it.

[PATCH] par2 creating support

Status in duplicity - Bandwidth Efficient Encrypted Backup: In Progress

Bug description:
OK, this add support for creating par2 recovery files for every file that gets 
uploaded to the backend.

- can be enabled by passing --par2. If the backend already contains par2 files 
there is no need to pass the --par2 option.
- the par2 files are created just before the upload of the file so this will 
not break the asynchronous mode.
- all par2 files are preserved in the local cache and uploaded to the backend.


todo:
- add comments and logging
- add support for customizing the pa2 options currently 20% redundancy is used 
which might be an overkill or too little for someone
- don't use os.system and add error handling.
- add support for recovery.
  
Code review will be greatly appreciated. There are some very ugly hacks with 
temp files
