I'm running CentOS 4.3 on Intel. I don't have any tape device on my system for backup, but I have an entire disk (/dev/sdb) for backup ... my question is:
How can I backup ALL my filesystems to some place of my backup hdd (dev/sdb) using dump/restore?
I don't want to use tar.

'man dump' will tell you all you need to know.

Let's say you have two disks. There's the "system" disk with the root partition mounted as / and the "backup" disk mounted as /backup. If you did this:
/sbin/dump -0u -f /backup/rootbackup /
you would wind up with a dump image of your root filesystem on your backup disk and it would be called "rootbackup".
That works for me.
Cheers,

You can also check out 'dar' which is exactly for this. It backs up special device nodes, EA's etc. and has a catalog. I have used it many times for this kind of thing.
