[Duplicity-talk] Corrupted backups from Windows

[Nick Burch]

I've build Duplicity under cygwin, and full backups from it _appears_ to 
work fine.

However, any attempt to use the files (verify, restore, incremental backup 
etc) all break with an error about the tar file:

duplicity --no-encryption --list-current-files 
file:///backup5/dumbledore/dumblestore-2003-11-23/
Traceback (most recent call last):
  File "/usr/bin/duplicity", line 358, in ?
    if __name__ == "__main__": main()
  File "/usr/bin/duplicity", line 341, in main
    elif action == "list-current": list_current(col_stats)
  File "/usr/bin/duplicity", line 173, in list_current
    for path in path_iter:
  File

line 230, in combine_path_iters

line 171, in init_from_tarinfo
duplicity.path.PathException: Unknown tarinfo type


When doing a verify, I can see that the problem is with the .vol1.diff 
file. Unpacking it by hand with tar yields:

?rwxrwxrwx 544/8388607 68585259008 1970-01-01 01:00:00 snapshot/./ unknown 
file type ` '
tar: Unexpected EOF in archive
tar: Error is not recoverable: exiting now


Has anyone seen anything like this before? Anyone got any ideas what bit 
is at fault, so I can narrow down my search for the broken part?
