[Duplicity-talk] Duplicity failed after several successful backups

[Edward Jiang]

Hi Guys,
I've been using duplicity for backup for some time, but recently one of the backup started to fail, after "cleanup" command, it still failed to backup, giving the following error in the log:

Traceback (most recent call last):
  File "/usr/bin/duplicity", line 401, in ?
    if __name__ == "__main__": main()
  File "/usr/bin/duplicity", line 395, in main
    else: incremental_backup(sig_chain)
  File "/usr/bin/duplicity", line 174, in incremental_backup
    bytes_written = write_multivol("inc", tarblock_iter, globals.backend)
  File "/usr/bin/duplicity", line 83, in write_multivol
    else: at_end = gpg.GzipWriteFile(tarblock_iter, tdp.name,globals.volsize)
  File "/usr/lib/python2.3/site-packages/duplicity/gpg.py", line 241, in GzipWriteFile
    try: new_block = block_iter.next(bytes_to_go)
  File "/usr/lib/python2.3/site-packages/duplicity/diffdir.py", line 407, in next
    result = self.process(self.input_iter.next(), size)
  File "/usr/lib/python2.3/site-packages/duplicity/diffdir.py", line 487, in process
    data, last_block = self.get_data_block(fp, size - 512)
  File "/usr/lib/python2.3/site-packages/duplicity/diffdir.py", line 508, in get_data_block
    buf = fp.read(read_size)
  File "/usr/lib/python2.3/site-packages/duplicity/diffdir.py", line 338, in read
    buf = self.infile.read(length)
IOError: [Errno 22] Invalid argument


Anyone has any idea? Your help is greatly appriciated.

Best Regards
Edward
