that could very well be. it all depends how fast your link is and how much idle time your CPU has. your mileage almost certainly will vary. :) I could very well have done the wrong thing there, if I did indeed use some compression on the link. > The inconvenient with dd is that it copies all bloc, even those > unused... I read something if there is unused space on the partition, > create a file with /dev/zero, and next use gzip ah. yes. good idea. I don't remember if I did that before dd'ing the partition across the wire, but I might have. # dd if=/dev/zero of=bigfile.img <wait until we run out of disk space and dd exits> # rm bigfile.img it really does make a disk partition much smaller after compression. -- Carl Soderstrom Systems Administrator Real-Time Enterprises www.real-time.com ------------------------------------------------------------------------- Using Tomcat but need to do more?
