it depends how do you want to backup your disk, what kind of medium do you have ?
At least, I used two firewire disks (same size) synchronized with rsync, so, the backup took only few minutes.
For some servers, I used mondo/mindi to create backup on CD.

Is this a server or a destop machine. For a personal desktop, I like the dar/kdar programs.

It also depends on the filesystem used. A server may use lvm or use the xfs filesystem. They allow live dumps.

kdar needs an empty harddisk if I am right? Can it burn directly to DVD, with only 5GB free space on the / ?
thanks

Kdar was masked, but not dar itself. Kdar was unmasked a few weeks later.

From http://bugs.gentoo.org/show_bug.cgi?id=216063

Kdar was given last rites and pronounced dead at 3/5/08. But in the
process of being wheeled down to the morgue for cremation it sat bolt
upright in the gurney and coughed. Scared the sh*t out of the poor nurse.
kdar project is said to be dead

KDAR provides a convenient way to configure your backups. Then you can export the job as a bash script that uses the dar command. KDAR doesn't on it's own burn to a DVD. It can pause after creating each slice. Backing up to an external drive or a share would be a better idea. You can keep the entire backup in the external drive/share, or burn the slices to DVD and then free up the space.

If you save the restore job to a script, you could easily add the libdar and the dar program to a rescue disk. You could even add them to the initrd file.
