Of course, but on what medium did you intend to burn this ?
How much GBs are in use for your system ?

I wanted to put it on a CD
How do I check how much space I am currently using?
I have a drive with just the OS on it and other drives with data on them. I just want to make an ISO for the OS drive. |

Well I guess I'm using 1.8GB
How could I save an image of this in case the HD dies?
I've tried Ghost but it gives me errors reading right away. I know it's not the HD cause ghost gave me the same errors on another Gentoo install on a different HD. |

How about
| Code: | | tar -cjf image.tar.bz2 /mnt/gentoo/* |
?

1.8 GB to one cd ? Neato !
In other words - no, not likely.

This is how I backup my system:
Boot with your LiveCD or Knoppix, mount the root partition at: /mnt/gentoo. If you have independent
partitions for /boot, /usr, etc, mount them at /mnt/gentoo/boot, /mnt/gentoo/usr,etc respectively. Then:
| Code: | # cd /mnt/gentoo
# tar -cz --exclude-from /mnt/gentoo/root/exclude-list -pivO * | split -a 1 -b 700m - /path/to/mybackup.tar.gz-
|
You'll get several tarballs such as mybackup.tar.gz-a, mybackup.tar.gz-b, and so on, each of them
<=700MB (for CD burning). The file 'exclude-list' should be something like this (your current directory
is /mnt/gentoo):
| Code: | usr/portage/distfiles
var/tmp/portage
home/yourusername/music
home/yourusername/video
|
Note: You should have enough space for the generated tarballs.
To restore, make a filesystem on all the relevant partitions first, mount them properly (as described
above), then:
| Code: | # cd /mnt/gentoo
# cat /path/to/mybackup.tar.gz-* | tar xzvpf -
|
Of course, if you only have one tarball, you may just:
| Code: |
# cd /mnt/gentoo
# tar xzpvf /backup/gentoo-hda13.tar.gz
|
If necessary, you may also need to chroot and reinstall grub.

Install mondo rescue. It's in portage and will allow you to make a selective or full backup of your system and store it on bootable CDRs or DVDs. I think that's pretty much what you're looking for.
