you'll see the same thing with tar... tar+netcat will move data 3x as fast as rsync in many cases. rsync really is that slow, presumably because of all the checksumming overhead. so there are times when it's easier to just re-grab all the data from the remote side, if much of the data changes substantially between backups. -- Carl Soderstrom Systems Administrator Real-Time Enterprises www.real-time.com ------------------------------------------------------------------------- Take Surveys.
