Everything fails over time... (and in the long run we are all dead, at least according to J. Maynard Keynes :-) ) And you expect to be cloning the same images in 10 years time ?. DVDs have four major advantages, they are cheap, they do not deteriorate if not used, and they are robust (you would have to work hard to break one by dropping it), and they are small and light. (With recent technical advances giving possible storage significantly better than the current 4Gb, and with recent research pointing to a possibility of a 0.5Terabyte DVD they may become a much more useful long term storage solution). Hard drives are relatively expensive compared to DVDs, they are relatively bulky and heavy (what would prefer to carry up 5 floors a 10g DVD or a 1Kg drive caddy), being electro-magnetic media they will loose information if that information is not retrieved regularly, and they are relatively fragile (they are much more prone to physical shock damage). I do not think there is a question which is more appropriate this purpose at the moment. > If however you want to do this on systems which are remote or just not > on the network then you can use mondo-rescue to make an install set for This application is not one I know of, but I do think that you are confusing the requirements of a backup regime with the requirement of system cloning. - -- == I have always wished that my computer would be as easy to use as my telephone.

With different hardware any image of the windows part of the drive will be a problem. You will need safe mode and to fuss with drivers. For SuSE its much easier boot to mode 3; run SaX2 -l; init 5; login as root at which point the different hardware will be found click yes for the reconfiguration and your fine. I installed 9.2 this way on a PIII and moved the disk to the PII because the PIII had the DVD. As I remember Zenworks like VMware is for running multiple OS in parallel. But first you want an image for SLED and to dual boot. There I think its easier first start with your XP partition on what we will call the primary system which would be on hda1 and I assume no file exchange partition as users will have flash drives. Second partition the rest of the drive as an extended partition into which you will use Yast/Custome partitioning for the logical partitions for Linux. I recommend using the standard four, /boot / swap and /home as hda5, hda6, hda7 and hda8 respectively. Now here its tricky DVD backup will fail over time due to media failure so consider it temporary, harddrives can fail but overtime they have a longer shelf life than the ten years commonly assumed for CDR and DVDR. So backup your backup at least yearly and make incrementals if you make small changes. You can also mirror the drive onto another drive say in a USB inclosure. Yes you want to be paranoid. Now for that master image of the dual booting drive you just created. As long as the target device is the same or larger than the source you can use device-device to copy /dev/hda to /dev/hdb thats not just one partition but the whole drive byte by byte partitions and all. All that is needed is the target to be on the network somewhere hdb here is only an example as I have a system with two caddy because for a long time I only had one burner so I used sneaker net to bring the drive to backup. If however you want to do this on systems which are remote or just not on the network then you can use mondo-rescue to make an install set for all the programs on your system. If you want the Windows partition included it must be mounted at the time you run mondo. Then you will have an executable setup which boots and installs the disks. -- ___ _ _ _ _ _ _ || | | [__ | | | |___ |_|_| ___] | \/ -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: [opensuse] speaking of cloning....
2007/7/9, Pavel Nemec <[EMAIL PROTECTED]>: We boot standard system (small kernel with small initrd) from PXE/DHCP and than download "working" image over ftp. Then we unpack this working image and chroot in it. All configurations are done off-line, when image is prepared. Nice! I didn't know about that project. Redhat had a similar project called "statless linux". The main idea was to separate program and configuration files which are static, from dynamic system files (like in /var and in /tmp) and user files. This way they could mount root filesystem read only and one image could be shared among many clients. And one can install it either on hard disk, on CD(DVD), USB key or mount it as a NFS share. My personal opinion is that separation like this should be in the mainstream distribution in the first place. It makes cloning a lot easier. But dynamic files (/etc/mtab is the first example that comes to mind) kreept into parts of filesystem which are not meant to be dynamic. Files like this make liveCD-s and diskless clients dificult to prepare and update. Tools like unionfs would not be necessary if there was clear separation. System images made with KIWI are targeted for read-only media, so the separation of static and dynamic files is already there. That is why I find it suitable for system cloning. Of course for instalation on hard disk one does not need compresion and instead of building compressed image one could just make root filesystem tree and untar it. You could easily update the image and cloning would then just consist of taring the / again (and maybe /home and /srv). Wiki page on cloning seems very good Idea to me.

To some extent XEN creates a similarly dynamic environment. This is not system cloning, but has very similar requirements.

Combined with the regular backup of working data should allow rapid recovery from failure. If I add a new system component configuration can be deployed as either an additional custom rpm in (or separate from) the base image. puppet seems to do what Zenworks does.

Re: [opensuse] speaking of cloning....
Isn't KIWI(http://en.opensuse.org/KIWI) supposed to be the tool for that purpose? It can be used to make Xen images, so I see no reason why it could not make normal disk images. Anyway, I use autoyast for bootstraping the initial system and than use puppet(http://reductivelabs.com/projects/puppet/) for additional configuration.

For hardware flexibility, autoyast would be best, probably. However, another solution is simply to have a standard backup in a server, You fire up a live system in a client (usb?), then fire a script, either in usb or remote that does the formatting of the hd, mount the new empty filesystem into the live system, create the empty dirs for /dev, /sys, /proc, then the copying over of files from the server using something like rsync.

Spent a lot of time trying to get the Institution I used to work to (allow me to) test and hopefully deploy Zenworks ... No success *sigh* Looking at the AutoInstall documentation further it seems that it uses a XML based script which largely goes through the options described by other posters in cloning a machine. Real problem is that no mechanism seems to exist to import an existing package configuration into the script and support for non-SuSE supported applications and other things (e.g. Netbeans, Funambol) that deploy either using a bin or jar file is a bit limited. The documentation can be found at... http://www.suse.de/~ug/autoyast_doc/index.html there is some further work going on but I would suspect Novell may be moving towards a Zenworks based solution. For my purposes, I want to establish a base-line configuration that has some flexibility on hardware configuration, so the next time I have the kind of messy system collapse I have just had, or I want to move to new hardware I can quickly get going again. Unfortunately, binary level disk image cloning is not an option, and even it was does not have any flexibility (it is rare after a hardware related failure that one is restoring to the same hardware configuration).

This is a common problem in the Education sector where one needs to a lot of machines with apparently the same set of applications. The former does make this installation relatively straightforward, the latter could give major headaches if you need to put the same image on multiple machines, and would not be entirely useful when hardware components had changed What would be useful is a script could be run against an already configured machine, that created a DVD (or network image) containing all hardware related RPMS, only the RPMs required for the particular setup, Then installed a script which went through the hardware phase, automatically installed the defined RPMs and then generated unique keys/certificates as the installation CD/DVD does and only prompts for things like machine name for a configured machine The YaST AutoInstall system seems to have some of the this kind of capability but seems to be rather complex to use In fact page 2 of the manual for this answers your question to some extent... Ghost used to do this with Windows, but I do not think the consumer version does this anymore.

I can't seem to find any documentation for creating this same kind of "Master Image" for SLED. I understand that Imaging will be less of an issue with Linux due to the severely lowered privilege's regarding installing software into the core operating system, but I still need to be able to overcome any form of corruption quickly. I would also like to distribute a dual boot system image for few years.

I have, in the past, setup netcat, and copied a live system over to another system using dd. I needed minimum downtime, and thankfully it was not in heavy use at the time, nor did it have a database, all of which would have made for a disaster. But it was quick, dirty and got the job done. If you have an image you could do the same thing, from a non-live system. And it would prove rather straight forward I think, and should handle the boot records without having to do run grub-install or lilo afterwards. James - nice to see another NHer on the list...

That is a really complicated process, I imagine that you are telling me this needs to be done to each recipient? could it be set up as a pxe boot task?

How does on build an image for and what tools does one need to clone a master image to a lab? If the simple copying of an image leaves you with an unbootable system and even a tool like ACRONIS leaves you with tasks what then does one do? Is there a set of commands like "sysprep" for creating a master?
