I reported what appears to be the same issue in 2008: http://lists.samba.org/archive/rsync/2008-May/020892.html and I'm still seeing it today on 3.0.7. In my case, nothing else ever accesses the backup directory while rsync is running. I looked through the sources a while back and noticed that both receiver.c and generator.c can invoke make_backup(), either directly or via finish_transfer(). Could it be, then, that this error is caused by rsync's receiver and generator processes trying to initially create the backup directory at the same time? - receiver enters make_backup() - generator enters make_backup() - receiver checks if dir exists: No - generator checks if dir exists: No - receiver tries to create dir: Success - generator tries to create dir: EEXIST I don't remember seeing anything in the code that would prevent the generator from deleting a file while the receiver is updating a file. Both of those operations, of course, involve moving files into the backup directory. -- Jordan Russell -- Please use reply-all for most replies to avoid omitting the mailing list.
