The question is what filesystem version you are using?  We're assuming 
that its ext2, with the journalling laid on top which is then called 
ext3.  Dump would care, tar would not.

Something Chhristoph wrote triggerd another fading memory.  If there 
is a firewall involved, and the ports were opened ok, but the 
firewall see's no activity to 'keep-alive' within a certain time, it 
closed the ports.  This happened to another user at least a year ago 
IIRC.  I believe the cure was to extend the autoclosure timeing in 
the firewall rules.

And I concur with Christoph regarding dump.  Tar worked better for me, 
and it usually gives sensible error messages when it doesn't.  But 
tar versions vary too, and historicly we have been recommending only 
version 1.13-19 or 1.13-25.  There is an even newer version extant, 
but I can't recall if anyone here on this list has said it works 
correctly or not.
