Is there anything like Norton's Ghost that can be used to image a system? I have ghost 7.5 but it doesn't compress the system well at all. It sees Linux fine and dandy but thinks there is something like 70 gig of info on there (when it's a basic fresh install).

You dont need to do system images with linux. All you have to do is copy everything from one hd to another and then setup those certain files that matter. Linux doesn't try to restrict you like win2k by generating some type of encryption code base on your hd serial # or something.

Mmmm I don't want to come off in the wrong way here but this sound to me like over-simplifying the subject ..

Excuse the totally noob question here, wich files matter and in wich way should they be set up.

I've read a couple of topics on this matter;
https://forums.gentoo.org/viewtopic.php?t=28123&highlight=clone, where some recommended the find + cpio approach and others the dd way where the former were recommended due to flexability.

So I tried this;
Code:
find /mnt/srcdir -xdev | cpio -pvdm /mnt/destdir

but I've got various quirks and segfaults in KDE and suspect that this is the direct result of my actions (not handling the symlinks correctly??)

.... maybe I did it the wrong way but would still like a simple and sound "ghost" kind of way......

Ok, like you said there are several posts on this subject, and everyone does it their own way...

The way that I like to do it is to copy every thing from one drive to another using cp -a *, however there are a few dir's that will not copy over correctly. Namely /dev and no need to copy /proc because it is generated at bootup.

Ususally I prefer to make a backup dir in / for this so my cp command would look like this....
Code:

cp -a /bin /boot /etc /home /lib /opt /usr /sbin /tmp ...  /backup


And as you notice you will need to backup boot to do this.

Next, to take care of /proc just do mkdir /backup/proc

Then last I usually copy a stage3 over to /backup and then do
Code:

tar -xvjpf stage3* ./dev


That basically just untars the /dev dir only.

As far as copying over everything you now have it. If you were moving a primary install to an upgraded hard drive that would be replacing the other you dont have to do anything else (except install grub to mbr). Or if you were doing this for backup purposes you wouldn't have to do anything else either. If you need it on a dive letter other than what you copied it from then you would probably need to up date things like fstab.

Trust me it works, I have recovered my system once with this method (which I'm still using) and I also have a server setup to backup using a cron job every week.

Hope this helps....

Ok take my scenario for example. im placing my server into a building some 200miles away from me if i get rooted i need to re-install the whole server from a image of the HD including boot sector and all so i can intially find out how and where it was routed and make sure it doesn't happen again but at the same time ensure that the computer is keeping the same configs to ensure my users don't loose anything such as their passwords etc.

Is there anything like ghost so i can just image an entire drive to another and vice versa?

I've seen dd used for that, but I've not seen it for quite a while, so I can't say how.

Or can use dd. Just depends on what suits you better. dd is pretty easy if the drives are exactly the same (or if you just want to make an image file), even if they are in different machines. You can use netcat or ssh to pipe the output or input of dd over the network.

Partimage is great, but I dont think it does whole drives just individual partitions.
