The command I am using is: dump -0ab 32 -f luke:/dev/rsa0 When doing this I get a performance of less than 50KBs. This is to an Exabyte 8505XL tape drive which is capable of at least 500KBs when not compressing (though I am). If I, instead, pipe it through rsh to dd like this: dump -0ab 32 -f- / | rsh luke 'dd bs=32k of=/dev/rsa0 I get appx 500KBs (as expected). Does anybody have any ideas on what's going on here? Should I simply give up on rdump and stick to the rsh approach? Thanks, Bob -- Bob Willcox The man who follows the crowd will usually get no bob@luke.pmr.com further than the crowd.
