I have some updates: the full backup is passing.
The full process is taking about an hour and a half and I set a timeout
of 20 hours.
The 'sparse' problem could occur while doing a full backup ?
Because apparently, only the incremental one is hanging.
My target is a linux.
If it can help, here is the logs from the rsyncd of my target:
2013/09/04 08:00:23 [32503] connect from backupserver (IP addr)
2013/09/04 08:00:23 [32503] rsync on . from backupserver (IP addr)
2013/09/04 08:00:23 [32503] building file list
2013/09/04 08:42:08 [32503] rsync: writefd_unbuffered failed to write 4
bytes to socket [sender]: Connection timed out (110)
2013/09/04 08:42:08 [32503] rsync error: error in rsync protocol data
stream (code 12) at io.c(1532) [sender=3.0.9]
and as I said before, the process on backuppc is still alive.
Thanks for your insights.
