[Bug 875676] Re: Backing up fails with 'IOError CRC check failed'.

 

Every time I start a backup I get the following error:
Failed to read /home/user/.cache/deja-dup/tmp/duplicity-7EsAky-tempdir/mktemp-hqHmHI-63: (<type 'exceptions.IOError'>, IOError('CRC check failed 0x6ae5ab23 != 0x78b803e5L',), <traceback object at 0x7f4f3cfa06c8>)
Deleting the cace dir does not help.

This issue showed up since some weeks but apparently I didn't change settings.
I'm using Ubuntu 14.10 with kernel 3.16.0-34-generic
deja-dup 32.0-0ubuntu1.1
duplicity 0.6.23-1ubuntu5
Any clue on solving and debugging?

Bug description:
  For 4 days déjà dup hasn't been able to perform a backup. It fails
  with the error

  Failed to read /tmp/duplicity-lJcUDl-tempdir/mktemp-o4LYSJ-1: (<type
  'exceptions.IOError'>, IOError('CRC check failed 0x8434f7d2L !=
  0x3d503338L',), <traceback object at 0x9fe0554>)

  There is another similar bug #676767 where deleting ~/.cache/deja-dup
  helps. In this case it doesn't.

  I'm quite certain that my backup drive isn't corrupted. (It's a
  raid5.) I'd be happy to provide any additional information needed.
