duplicity fehler

[Michael Vogt <lists@moep.dyndns.org>]

Hallo liste.
Ich nutze zum sichern meiner Daten dass Programm "duplicity". Dass ging 
bisher auch ganz gut.
Seit neustem tritt jedoch folgender Fehler auf:

Traceback (most recent call last):
 File "/usr/bin/duplicity", line 373, in ?
   if __name__ == "__main__": main()
 File "/usr/bin/duplicity", line 367, in main
   else: incremental_backup(sig_chain)

   bytes_written = write_multivol("inc", tarblock_iter, globals.backend)

   else: at_end = gpg.GzipWriteFile(tarblock_iter, 
tdp.name,globals.volsize)

   data, last_block = self.get_data_block(fp, size - 512)

   buf = fp.read(max_size)
 File "/usr/lib/python2.4/site-packages/duplicity/librsync.py", line

   self._add_to_outbuf_once()

   if not self.infile_eof: self._add_to_inbuf()
 File "/usr/lib/python2.4/site-packages/duplicity/librsync.py", line 
94, in _add_to_inbuf
   new_in = self.infile.read(blocksize)
 File "/usr/lib/python2.4/site-packages/duplicity/diffdir.py", line 
338, in read
   buf = self.infile.read(length)
IOError: [Errno 5] Input/output error

Die /home-Partition funktioniert sonst jedoch normal (zumindest kann ich 
normal mit arbeiten), ein reiserfsck hat auch nichts geliefert.

Grüße,
