It is insecure, but no as much. Am I wrong here? Whether or not you'r wrong depends on what you're trying to secure. If the goal is to keep people from sniffing the dump, the ssh is more secure. If the goal is to keep root on the machine dumping from accessing the remote machine, then they are equally bad. On the other hand, doing tape operations over the network is sorta slow. I haven't been able to test, but you might get faster backups doing something like: dump dumptions -f - | ssh remotemachine dd of=remotetapedevicename bs=blocksize If you do some tests of this, please let us know the results. http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
