As to that a quick web search indicates previous reports:

https://unix.stackexchange.com/questions/68775/rsync-timed-out 3
«It looks like the server times out on the SSH connection level.»
«Since the timeout appears to happen when rsync is creating the checksums»

«it seems - in my case at least - to be related to the delta-xfer algorithm»

Title:
  Getting error message:  error in rsync protocol data stream (code 12)
  at io.c(605) [sender=3.0.9]

Status in rsync package in Ubuntu:
  Confirmed

Bug description:
  1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu
  Precise 12.04LTS

  2) The version of the package you are using, via 'apt-cache policy
  pkgname' or by checking in Software Center

  Installed: 3.0.9-1ubuntu1
    Candidate: 3.0.9-1ubuntu1
    Version table:
   *** 3.0.9-1ubuntu1 0
          500 http://archive.ubuntu.com/ubuntu/ precise/main i386 Packages
          100 /var/lib/dpkg/status

  
  3) What you expected to happen

  I was using rsync to backup my Home DIrectorys' contents and at one
  point in the backup it gave me this error:

       Downloads/Windows.7.Ultimate.32-64Bit.(2011-02-09).iso
    3809312768  83%   21.03MB/s    0:00:35  
       rsync: writefd_unbuffered failed to write 4 bytes to socket [sender]: Broken pipe (32)
       rsync: connection unexpectedly closed (70735 bytes received so far) [sender]
       rsync error: error in rsync protocol data stream (code 12) at io.c(605) [sender=3.0.9]
       

  This only came about when it was trying to copy my Windows ISO from my
  directory over to my backup drive that I have formatted in EXT4 - so
  I'm not sure of the issue it's having.

  This is the command I used to backup:

  rsync --progress -rEog --exclude Videos/ --exclude converted_music/
  --exclude VirtualBox\ VMs/ --exclude virtual-drives/ --exclude
  Backup_of_boot_sectors/ --exclude examples.desktop --exclude Music/
  --exclude .ecryptfs --exclude .VirtualBox/ --exclude .thumbnails/
  --exclude .thunderbird/ --exclude .vidalia/ --exclude .teamviewer/
  --exclude Templates/ --exclude sources.list --exclude wary-5.3.iso
  --exclude Public/ --exclude .cache/ /home/alex/ /media/backup/12.04
  -Precise-backup_4.23.2012/

  
  Please look into this for me.

  Thank you
