If by "directly" you mean that you want an image copy of the partition,
then this will work:
dd if=/dev/sda1 of=/dev/st0
(You may need to change the device identifiers, of course.)
In most cases, though, this is a very poor way to back up a system, since
it doesn't give you file-by-file restore access, and you'll only be able
to restore to a partition of the EXACT same size, which may not be
possible if, say, the hard disk dies. OTOH, it may be the only way to
back up partitions that use filesystems Linux doesn't support. For
instance, if you've got a BeOS partition, that might be how you'd need to
Instead of doing a raw partition dump, you should probably look into any
of the many backup programs supported by Linux. Most Linux systems
include both cpio and tar, and these can be used for a backup. For
instance, to back up everything using tar, you could issue this command:
tar cvf /dev/st0 /
There are lots of additional options you can use, too.

One I've used on occasion is KDAT (http://sunsite.auc.dk/qweb/kdat/).
KDAT is loosely affiliated with the KDE project, but you don't need to be
running KDE for it to work. It's basically a GUI front-end to tar.
