Re: [CentOS] backing up my system with dump

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.

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.
