I don't know if it's relevant, but rsync can be extremely slow at transmitting large sparse files (sparse = with holes in). The sender scans the holes (which is very slow for many gigabytes), and might even send zeros (I don't remember), but the receiver doesn't write anything. This means when there's a timeout, you have to start again from the last non-hole in the file - this is annoying if a hole is many gigabytes long and takes hours just to transmit the hole. The difference in size between "du" and "ls -l" will show if your vmdk is a sparse file. -- Jamie -- Please use reply-all for most replies to avoid omitting the mailing list.
