The filesystems _are_ actually mounted, yes?
Not merely mentioned in the fstab?
What does "df -lk" say?

That generates a tar file with paths starting "/mnt/hda1/blah...".
If hda1 is supposed to be being copied onto / on the target system you
want this:

	cd /mnt/hda1
	tar cf - . | ssh root@xxxxxxxxxxxxx 'cd / || exit 1; tar xf -'

Does that do what you intend?
