Bruno, I have been chasing this problem also, but I have additional problems. One is that the backup occasionally hangs without any error message, the other, more frequently, is that the backup fails with an additional message "corrupted MAC on input". The "MAC" is not the address of the NIC, but "Message Authentication Code", part of the ssh protocol.
It appears that most people believe that this is due to ssh's reaction to a hardware error. People have reported faults with memory, cables, NIC's, wireless and routers. This is consistent with the fact that the only machine having the problem on my home network is the one using a wireless NIC. The solution seems to be to fix the hardware, which as yet I have been unable to to, or to reduce the strain that "rsync" puts on the system. I have done this by adding the "rsync" options "--whole-file" and "--bwlimit=500". This more than doubles the time for the backup, but it has worked so far. The first option causes "rsync" to transmitt the whole file rather than only the bits that are changed, the other limits the bandwidth to 500k. If it is all due to ssh and hardware it makes me worry about the resilience of ssh. Surely its protocol should be able to retry on corrupted data? I don't know... Another solution maybe to use "rsyncd". This should avoid using ssh as the transport. I haven't tried this yet. Hope this helps, Peter.
