CentOS 5 Hardware :: Cloning Image Of Hard Disk

Nov 7, 2010

I just invested nearly 12 hours configuring a CCTV system using CentOS 5.5 Server and Zoneminder. I have it setup just the way I want it. I would like to make a clone image of the drive just in case disaster strikes (lightning strike, failed hard disk, etc). In the Windows PC world, I use a program called Ghost to make a mirror image of a hard disk. I power the computer down, run Ghost to make a block level clone of the drive, then power it back up. Can I assume that will work with CentOS without problem?

In the computer now is a 320GB SATA drive. One partition on it is swap, and the other is ext3. There is no raid setup on the drive. I have an identical 320GB drive I could use and keep it in the computer unplugged from the power and not spinning. That way if anything ever happens, I can power down, move the power and data cable to the new drive and power it back up. Granted, I will lose any new config and database changes, but it will be a lot better than starting back at square 1 and reconfiguring the entire OS and software.

Ubuntu :: Cloning Bootable Hard Disk

Feb 21, 2011

Recently my had disk crashed. It has taken me over a day to install and setup the drive - time I can't really afford. I'd like to know how I can clone a second as a bootable copy of the main hard drive and update from time to time. Therefore if the main hd fails again, I can simple boot from the second drive.How can I do this? I have two sata drives in the box, running 10.10 desktop.

CentOS 5 :: Build A Bootable System Image On An Attached Hard Disk On A Running Machine?

Feb 27, 2011

I would like to build a bootable system image on an attached hard disk on a running CentOS machine.The hard disk would be moved to a headless server, where only SSH access would be available. It seems that all the documented install methods assume that the installation runs on the taget machine. In this case, I would like to create a bootable system image of CentOS on a running host system. The new install mage would generally have a newer version of CentOS than the running host system where the image is created. Also, I would prefer
to do a text-based install.

The reason for all this is that I have network access to several remote machines. I can ask disks to be moved between machines, but I have no physical access. In order to do software testing, I would like to have several system disks with different installed CentOS versions. It would be easer if I could build the system disks on one single machine. The hardware an all machines is very nearly identical.

General :: Use Hard Disk Image Like A Regular Hard Disk?

Apr 6, 2010

If you have a hard disk image (including partition table, multiple partitions,...), is it possible to let Linux treat it as a regular hard disk?

By "regular hard disk" I mean I would like to have the image show up as, for instance, /dev/hdx and its partitions as /dev/hdx1,...

(I know I can mount one of the partitions in the image using "mount -o loop,offset=x ..." but I don't really like this option.)

General :: Creating Image Of Hard Disk

Jul 28, 2010

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?

SUSE :: Need To Copy DVD Image To Hard Disk Of Computer

Jan 5, 2010

After I burn the DVD image, I put the disc on the computer and boot. The installation screen appears, the acknowledgement screen appears, then the installation checks my system and gives me a yast window with an error about something related to URLs and repositories. I cannot continue with the installation.

I am 100% new at this and thought it would be as easy as installing ubuntu (which I installed on a laptop and works flawlessly).I am trying distros and opensuse is compatible with my video card right out of the box apparently, so that's why I chose it for my desktop.Do I need to copy the dvd image to the hard disk of the computer I want to install opensuse on, and use the dvd to boot as well?

Ubuntu Installation :: Creating An Exact Image Of A Hard Disk?

Sep 8, 2010

this is in the wrong section, but I wasn't sure where to put it. Since the background to my problem is kind of long winded I've split this post into two sections: Short version of problem

I have a PC that has two internal drives: one drive (drive A) is empty, and the other (drive B) has a copy of windows vista installed. At the moment the PC boots from drive A. I'd like to transfer everything from drive A to drive B, so that this new disk will boot and behave nicely and windows will still function.

Is there any easy way to do this in ubuntu? I'm guessing I can use something like dd, but will this copy the boot sector and will I have to mess around with the partition table? Long version of the problem

Today I built a new PC for my dad with two internal drives. He was previously using vista on a laptop which died a few days ago, and I'd like to install vista on one disk of the new PC, and ubuntu on the other disk.

He has a licensed copy of Vista for his laptop, but it came as a "system restore" disk, and so I can't install vista directly onto the new PC. I have an identical laptop to his, so I took out the drive from his laptop, put it in my laptop, and did a "system restore" from the disk that came with the laptop. I then took out the drive from my laptop, and put this inside the new PC. It boots up fine, and I installed all the necessary drivers and etc to make windows work.

Now instead of using a slow/small laptop drive inside the new PC, I'd like to be able to clone the data on laptop disk and this onto one of the bigger/faster internal drives of the new PC. How can I do this from ubuntu, so that the new drive will boot windows?

I'm fairly certain it can be done using dd, but how do I make sure the information in the boot sector (or partition table) is correct for the new drive? I'm asking this because when I put my laptop drive into the new PC initially, I had connected it as an external drive, and when I tried booting from this there was an error, something like "Invalid partition table" (I think). I figured that when I did a "system restore" on my laptop, the drive was the only drive available, so this would be HDA, or SDA in the boot record of that disk. But when I added it to a system where other drives were available, it was no longer at that same location, so the boot loader couldn't find the data it was looking for to load the system.

Software :: Boot From A Image Transferred To Internal Hard Disk?

Jul 20, 2010

I have a dvd I want to boot from, on a certain laptop. The problem is this:

DVD will NOT boot in laptop [1] with this DVD.
DVD WILL boot ok in laptop [2] with this DVD.
- Conclusion, DVD is ok.
* laptop [1] and laptop [2] boots other media in the cd/dvd drive ok.

I can see all files on DVD in both laptops. As a workaround I copied the DVD image off the DVD drive to internal hard disk with following command and the result was as follows:

- result of dd command
# dd if=/dev/sr0 of=/dev/sda4
6298816+0 records in
6298816+0 records out
3224993792 bytes (3.2 GB) copied, 473.18 s, 6.8 MB/s

How do I make that partition [/dev/sda4] bootable ?

Ubuntu :: Restoring Disk Image To A Smaller Hard Drive Than The Original?

Jan 13, 2011

I am looking for an Open Source software making it possible to make a disk image of an Ubuntu installation as well as a Windows XP installation.I have checked out Clonezilla which almost solved the problem. However, the disk to which you restore needs to be the same size or bigger. I want to restore the whole thingo a smaller disk than the original.I am considering getting myself an SSD disk which will be considerably smaller than the 160 gb disk I have right now. I need it to work for Windows as well. Unfortunately I can't get rid of Windows quite yet I often participate in webinars on GotoWebinar and they do not support Linux ...

Ubuntu :: Dd For Cloning An Image To A Partition?

Apr 13, 2011

have a binary image that I can copy to a partition and have done so successfully in the past. The image is smaller than the partition size, and everything is all good. However, I noticed that in copying the 5 gb image to the 9 gb partition there are 4 gb that are unnoticed by the system. It still registers the partition at the correct size in Gparted and Disk Utility.

General :: Cloning PC Image To External - Read Error

Nov 2, 2010

I have a pc I want to clone and it has 2 partitions sda1 which is vfat and sda2 ntfs. When I had mounted my external hdd it was seen as sdc1 and my Knoppix boot as sdb1. I tried using the following command to copy the pc image to my external but when it gets to 26Gb it gives read error.

mkdir -p mybackup
mount -t ntfs -o rw /dev/sdc1 ./mybackup
dd if=/dev/sda of=./mybackup/780.iso bs=4096 conv=notrunc,noerror

Where am I going wrong? Is there anything wrong with my above commands?

Server :: Image Cloning Application (Running Backup Remotely)

Jan 14, 2010

I need to backup my active production servers (yeah it's too late now) with image cloning application that were running RHEL3-5. The problem is I need to run it remotely from my office. Most of the software I found either need to use bootable cd or need to unmount my partitions which is I wasn't allowed to since it's a production servers. I also tried dd but it consume too much time, sector by sector cloning and empty disk space also included so the file created also big in size.

CentOS 5 Server :: Make A Disk Image Of An Active Partition?

Jul 13, 2010

Is there any way to make a disk image of an active partition? I have to get a complete backup (partitions, MBR, all data files) of my server without bringing it down to do it. I want to have a backup that, in the event of a system failure of any sort, I can quickly restore onto a new, bare hard disk and have the system back up and running. The windows equivalent of this would be something like Drive Image XML, this is the functionality I am looking for.

CentOS 5 :: Running Centos From USB As Hard Disk?

Sep 1, 2010

I have seen that is possible to boot from a USB stick and use a USB memory as hard drive.I have a server enable to hold 6 sata drives 3.5", But I want to use the 6 drives and make a Raid-5 setup for backups 5 -1 spare. /boot cannot be on a raid-5 level 0 or 1. But I want to have redundancy for my OS, them I can install Centos on a Raid-1 using 2 disk, which let me only 4 for the raid 5. I will run a backup I want to have a lot of space.

Using 4 disk for raid-5 2 TB I will have 6TB no spare, no spare is not a good option at least I will prefer 1 spare.Well, I was thinking, the server MoBo have USB support, if I open the box I can see the small entrances, If Centos let me installed on a USB memory drive, can I trust a USB memory stick?t night with bacula.

Ubuntu :: Cloning Disk W/o Unmounting

Apr 18, 2011

I've spent the better part of an afternoon looking for a solution to a problem: backing up my installation of 10.10 as an image file to an external hard drive. My research has yielded a lot of suggestions for clonezilla, dd, and partimage/particlone, but those don't seem very appealing, due to a number of issues (can't backup live, copies free space as well, doesn't handle ext4, etc). Also why is clonezilla 150mb?

I'd like a simple solution that can clone an entire disk (used space only) to an explorable image file on a separate hard drive and be able to do it while the operating system is running on the disk. I used to use apricorn ez gig to do this on windows and it worked like a charm, but I can't seem to find a similar solution that creates and explorable .iso image file with linux. I've used superduer on osx, which is awesome and i wish there was something like that for ubuntu/linux.

Using an app like this saves re-installing the O/S, software, configuration and allows making a disaster-recovery drive.

General :: Cloning A HD Or Partition Onto A Different Hard Drive

I want to move the entire contents of my backup HD to another HD. I could manually copy everything, but I was hoping to clone the entire backup hard drive. I tried to do it with Gparted, but as far as I can tell, I can't clone between drives, only between partitions on the same drive (I've done that before). So how can I do this in Linux? I think one of my drives came with a cloning utility on a CD, but I'm not sure I still have the CD.

Ubuntu Installation :: Cloning To Smaller Disk?

Jun 3, 2010

I have my Mythbuntu 9.10 environment installed on an old 160GB PATA disk and have just purchased a new 64GB SSD that I want to transfer my installation to.In the past I've just used ddrescue to clone disks, however in this case the source disk is larger than the destination disk so it won't work. I only have a few GB of actual data on the 160GB disk, so the 64GB SSD is definitely going to be enough for me.

I guess I need someway of either cloning so that only the actual data and not the partition is brought across, or possible shrinking the partition(s) first on the source drive and then using the same ddrescue method I've used in the past.Just looking for some assistance on what method is the best/most reliable?
