General :: Creating Image Of Drive Partitions
Jan 6, 2011
I have what I thought was a simple task of creating ISO images of my Windows 7 system partion and boot partiton (the C drive) on my physical hard drive that I could use to load Windows 7 onto a virtual machine. Anyway, I'm running Ubuntu off the CD drive and I can see my drive partions (checked using the fdisk -l command). I have tried many iterations of the mkisofs command, but no matter what I do I get the error message: unable to open disk image file 'dev/sdb/win7sys.iso'. I don't understand why it's trying to open an ISO file it is supposed to be creating. The -o FILE option sets the output file name, so the message makes no sense to me. Below is an example of a simple and longer version with more options that I have tried to create an image of my sytem partiton (sda1) and save it on an external drive (sdb) with the file name: win7sys.iso (the next step I think would be to create or merge both partition images as one iso file for the VM). But I can't get past this error.
Can anybody tell me what I'm doing wrong?
sudo mkisofs -o dev/sdb/win7sys.iso /dev/sda1
sudo sudo mkisofs -input-charset iso8859-1 -V win7sys -o dev/sdb/win7sys.iso /dev/sda1
* Note that the output after the -o parameter is the desired destination /dev/sdb (my external drive) for the image file and /dev/sda1 is my Windows 7 system or boot partition (sda2 is what Windows sees as the C drive).

I am installing Linux on some spare space I left over from my previous two Windows installations.
From within Linux, what's the most risk-free way of imaging these two partitions and saving them to a single image file or archive? I want to preserve the entire partition because I have no idea what I may have forgotten to copy. What is the most suitable program that can do this?
Is there any way to run the partition in a virtual machine at a later date?
After this is done, I want to delete those old partitions and extend my Linux ones.

however, I couldn't find a place in which it would really fit well. I have 2 hard drives, that I want to backup. I've heard of servers and things like that using a hard drive image. Is this similar to a disk image? What are the benefits of using hard drive imaging as opposed to using DVDs? And perhaps most importantly: how would I go about it using Fedora 10 (64 bit)?

I have a hdd with WindowsXP that I'd like to install on Virtual boxe. The hdd is currently in use, but can put in enclosure to perform operation. To do the planned operation, what is the best way? Do I need make iso image of hdd? Or can I install directly to vboxe?

Right direction regarding the creation of a bootable Linux Image for PXE booting. I've already consulted google and the other obvious sources I could think of, but it seems that PXE is mostly used to install stuff, which isn't quite what I need.
The goal here is to have a pool of computers that boot from a central source so maintenance is less of a hassle. Installation of the individual PCs is not desired and I'm supposed to provide a functional Linux via PXE booting.
What I need is basically a way to turn a working Linux into an image that can be booted via network. Or to recreate that Linux as an image that I can boot.

I am new to the Linux world and I am not sure if what I am trying to do is achievable or not. I am trying to make an image of my existing drives running Linux on a USB and I want to use the same image off the USB to clone more bootable hard drives. Something like what Ghost does in windows. The problem is using 'dd' the image is too big ( I have 1tb drives ) and then I am not sure how to convert these images back on to new drives so that they boot in the OS as well. i am not sure if there is a utility that would let you do that?

I want to create a compressed ISO image file and mount that file to one of the virtual drives and access the content (read-only) without worrying about manual decompression/extraction.For Windows and Linux (Ubuntu) OSes.

I am trying to install Linux (the distros I have attempted it with are Arch, Fedora, Ubuntu and Mint) on a USB drive and make it work like a removable hard drive, keeping programs and settings. I tried it manually at first, partitioning the drive with Fedora's "Disk Utility" and dd'ing a Fedora 13 iso over. I should note here that I have definitely configured the BIOS correctly, enabled booting from removable media and set it as the default with all other devices disabled, but that I have never actually booted from USB before with this motherboard. On bootup I got
Code:
DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER
I then tried it with Ubuntu 10 and Ubuntu's "usb-creator". This was apparently successful, but on bootup I got:
Code:
missing operating system
DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER
I downloaded UNetBootIn, but the application kept saying I needed "p7zip-full", which I couldn't find anywhere. I then got Fedora liveusb-creator, but whichever iso I give it I get this error:
Code:
Unable to find LiveOS on ISO I looked at the source code and it seems to be looking for a directory named LiveOS on the iso containing the files "squashfs.img" and "osmin.img" Here is the code (usr/lib/python2.6/site-packages/liveusb/creator.py, line 575):
Code:
def extract_iso(self):
""" Extract self.iso to self.dest """
self.log.info(_("Extracting live image to USB device..."))
[code]...
I couldn't find much about what LiveOS actually means and why I need it to create a bootable USB, so if anyone could tell me more about this that would be great. Is this (the .img files) the only thing distinguishing a "Live" OS from a non-Live one? I looked in my Ubuntu live CD and there was no such directory, but it works perfectly well. In case it would make a difference, the stick is 8GB and branded duracell, not sure what manufacturer it is.

I recently bought a Buffalo 500GB ministation usb with "optional disk encryption". Turns out, I'm having one hell of a time trying to remove the "optional" from the drive. I figured I could just delete the program that is on the disk, and go on my way. That doesn't seem to be the case.
fdisk /dev/sdc1, then "p" showed that there were 4 partitions. So I deleted them one by one. "n" gave me a new partition. "t" I used 87 because I will be using it on windows. Then "w" to write everything.
mkfs -t ntfs /dev/sdc1 - all went well.
fsck -f -y /dev/sdc1 - all went well
Then I took the removed the drive and plugged into Windows only to find that the "optional" is still there. It actually creates a virtual drive with the "optional" software. So I tried it over again. I tried fdisk only to see that the partitions were back (as if they were never removed). I removed them again, and used primary partition as linux and wrote to disk. As a hunch, I checked permissions. Can't remember what it said, but I did change them.
chmod 777 /dev/sdc1
Then in a last hope of desperation, before coming to work today, I decided to dd the drive.
dd if=/dev/zero of=/dev/sdc1 bs=4k conv=notrunc
Is it possible that the "optional" stuff is actually hard coded onto a chip, or something inside the drive and I may never get rid of it?

I was given a forensic Image which I now know is a DD image of the drive (Vista) and am trying to mount the image or extract the image to another drive. I'm not sure of the extention type or if the image is a partition or the entire drive. I think it is the entire drive.
Is it possible to mount a DD image to a device. If I can't do that I just want to extract the files to run some programs against the drive. Can I view the files under Ubuntu or do I have to remove the drive and stick it into a Vista computer.
I purchased a second drive today and was hoping the command line would be something simple.
Or am I on the wrong track, should I be doing this all in a windows environment. The reason I picked ubuntu was because of the reporting tools.

We are in the process of pruning our directories to recuperate some disk space.
The 'algorithm' for the pruning/backup process consists of a list of directories and, for each one of them, a set of rules, e.g. 'compress *.bin', 'move *.blah', 'delete *.crap', 'leave *.important'; these rules change from directory to directory but are well known. The compressed and moved files are stored in a temporary file system, burned onto a blue ray, tested within the blue ray, and, finally, deleted from their original locations.
I am doing this in Python (basically a walk statement with a dictionary with the rules for each extension in each folder).
Do you recommend a better methodology for pruning file systems? How do you do it?

I have a dell poweredge 2950 server which had red hat on it. I have installed ubuntu on top of it. I have replaced master boot record during the installation of ubuntu as I dont want use red hat anymore. During the installation it asked me for the space I wanted to give for Ubuntu and I provided 10GB. Now I can use only 10GB of my harddrive until I mount other partitions correct?
So when I type sudo fdisk -l I get the below printed:
Code:
Disk /dev/sda: 146.2 GB, 146163105792 bytes
255 heads, 63 sectors/track, 17769 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes

I'm trying to create some Linux partitions to install Slackware on my Lenovo W510 notebook and I'm getting some partition "errors" when using fdisk or cfdisk during the Slackware install. I have a feeling this is due to the hidden system restore partition and was wondering how others have dealt with this.

I have been using GHOST for quite a few years to back up my Windoze partitions from NTFS to a series of images on a fat32 partition. I usually boot off a DOS7 bootable CD and simply ghost over to the fat32 partition.
I am rebuilding my laptops and desktops to dual boot Windows7 and Suse 11.2
My goal is to create restore images from my NTFS and ext3 partitions into directories on the fat32 partition for a restoration to my "gold baseline" build after any corruption.
My partition layout is below. This is output from gdisk.exe in DOS7. It's an 80gig drive.
1 = Windows-7
2 = /boot
3 = swap
5 = /
6 = /fat32

I'm currently running a Ubuntu 9.10 64bit machine with one of those 2TB WD disks that does have 4KB blocks.Unfortunately the current partition layout is misaligned, so I plan to back up my home directory and start fresh with a 10.04 install, trying to make the partitions aligned as suggested here:what I'm wondering is, does the 10.04 partitioning program take care of the alignment today or I have to resort doing manual partitioning with a separate tool?

My chief file server (Dell PE R300) died last week with a disk error, and because it serves the /usr/local and /home partitions via NFS to my ~60 desktops, nobody could do any work until I managed to rig up another server and pull data off the backups. I'm using RHEL 4.To avoid this in future my plan is to knock up a dual server solution with DRDB and Heartbeat.In the meantime, is there a better way to allow desktop users to carry on working as normal, without relying on the file server too much? i.e. something better than NFS but not LDAP (I don't want to implement this just yet as the organisation as a whole may do this in the future)? My users need to be able to access the same home area on any linux desktop managed by me.Also, to implement DRDB/Heartbeat, it might be best to have the home areas on an external array, is that right? Can anybody recommend some hardware?

CentOS 5.2 64bit 2.6.18-92.el5xen. Use rsync with --link-dest for nightly backups, works well. Was recently asked to start weekly backups to an external drive for off-site storage. The regular syncing works but hard linking seems to be ignored. So the backup is long with no space saving advantage. Here is an example of the command being run:
rsync --stats -axzvl --numeric-ids --delete --link-dest=/mnt/DISASTERBACKUPS/austinBackups/backups/2009-08-21 /AUSTINBACKUPS/backups/2009-08-24 /mnt/DISASTERBACKUPS/austinBackups/backups/

I've performed a clean install of Linux on my system, and would like to create a snapshot of my whole disk so that I can go back to a fresh state immediately.
I used to use DriveImage XML and it was a FANTASTIC program, but unfortunately the boot CD containing it can only be created by having Windows installed. So it might be time to explore a new program that is equally simple and effective as that one.
I'd like your recommendations of imaging programs that are free, and that work off a boot CD/DVD (because the live backup thing generally takes much longer for imaging an entire disk).
One thing I liked about DriveImage XML was that it stored the backup in a fairly readable format, so if one day DriveImage XML were no longer available you wouldn't lose your backed up data. Any such programs?
Also, would these programs work for a drive that contains an encrypted root partition (i.e. enabling the encryption checkbox in the CentOS installation)?

I am rebuilding a bunch of servers and want to do it right. They are Dell R200s and R300s with on-board LSI SAS1068E SCSI controllers with 2 SATA drives. The only RAID level supported on these cards is RAID 1. So, to the server, we have 148GB of space to deal with. They currently run 32-bit Ubuntu 8.10; I will be installing x64 Ubuntu 10.04.
I have always seen that it is best practice to partition in such a way that /boot, /var/log, /temp, and /home for example are separated out from /. Usually this is on a RAID5 or higher box. Is there any benefit to doing that sort of thing on a RAID1 box? I realize that this is in some ways a matter of opinion, but I would like the opinion of folks with experience. I'm pretty new to Linux in general.
The main services running on these boxes are Apache2, Tomcat6, MySQL, and Java.

My home server runs Debian Lenny, and I'm about to upgrade the system drive to a larger drive.In the process, I want to take the opportunity to reorganize the partitions and resize them. For learning purposes, I'm planning to migrate from an MBR partition table to GPT.Because of those two changes, I can't just run "dd if=/old/drive of=/new/drive" (well, not without lots more work afterwards). I could use the debootstrap process to get a fresh installation on the new system drive, but I used that technique during the last system upgrade and it's probably overkill for this.Can I just copy the partitions from the old drive to the new?Will "dd if=/dev/hda1 of=/dev/hdb2" work, assuming /dev/hdb2 is larger than /dev/hda1? (If so, the filesystem can be resized to take advantage of the new larger partition, right?)Would parted (or gparted) be a better tool for copying the contents of the partitions?

i feel like this is a stupid question as i have seen many different ways to make a debian live cd, but the only way i understand is remastersys.i am trying to make a snapshot of my own debian unstable (sid) to be capable of re-distribution. remastersys will ONLY work on ubuntu, lenny, and squeeze.if anyone knows of any relatively simple tools i could use or could write an easy how too that would be very much appreciated. i am attempting to stray away from ubuntu and ubuntu based distros and use debian instead, although i cant find any distribution based on debian that i really like (maybe linux mint debian edition based on debian testing), but i really want the software right out of unstable (sid) and i would like to be able to make a distribute-able snapshot for myself and others that may be interested. (xfce + compiz + others, hopefully plymouth, out of the box). i have made some very good headway on this, but i dont know how to make a live cd out of an installed system without remastersys.

Could anyone recommend a method of creating a full disk image. I have the Acronis bootable media, would this work to backup Linux partitions? I'm thinking that Acronis doesn't know or care what is written to the disk as it works at a lower level.

I have installed Centos 5.4 and then on top of that i have been installing many softwares over the time ( like pbx system , web console , billing etc.) and now it has come to a quite stable stage. the problem is i have to move this installation to another machine with different config etc. even have to install it on multiple systems. the idea is to create a bootable linux iso of the current machine with all the softwares so i can simply put it in a different machine and make it install and run without much fuss. is creating a linux appliance the only solution ? or is there any way to backup the current machine in an iso format and then install it on another machine? also i would like to make this completely hardware independent.

I am working to create a new base image for our RHEL5 setups, and I wanted to make sure we are creating a functional, but secure, image. Can anyone point me to some writeup's that might provide some illumination on this potentially daunting task? Basically, I'm concerned about what packages are okay, which should be avoided, and what other caveats that I might not think of when putting this together.

I followed the instructions here: [URL] and then here: [URL] and installed the necessary packages. But when I try building the minimal image as a test, I get lots of errors, as seen in the attached build log. There are lots of things that don't seem to work. Is this project at a state where it's not currently usable? Or do I have a problem with my system configuration? I was running at root.
