Clonezilla<\/strong>\u00a0is one of the greatest Open Source backup tool for Linux. The absence of a Graphical User Interface combined with a simpler, fast and intuitive guided command line wizard that runs on top of a live Linux Kernel makes it a perfect candidate back-up tool for every sysadmin out there.<\/p>\n

With\u00a0Clonezilla<\/strong>, not only you can perform a full backup of a device data blocks directly to another drive, also known disk cloning, but you can also backup entire disks or individual partitions remotely (using SSH, Samba or NFS shares) or locally to images which can be all encrypted and stored in a central backup storage, typically a NAS, or even on external hard-disks or other USB devices.<\/p>\n

In case of a drive failure the backed-up images can be easily restored to a new device plugged-in into your machine, with the remark that the new device must meet the minimum required space value, which is at least the same size that the failed backed-up drive had.<\/p>\n

In simpler terms, if you clone a\u00a0120 GB<\/strong>\u00a0hard-disk which has\u00a080 GB<\/strong>\u00a0free space, you can\u2019t restore the backed-up image to a new\u00a080 GB<\/strong>\u00a0hard-drive. The new hard drive which will be used for cloning or restoring the old one must have at least the same size as the source drive (120 GB<\/strong>).<\/p>\n

In this tutorial we are going to show you how you can clone a block device, typically a hard-disk on top of which we run a CentOS 7 server (or any Linux distribution such as\u00a0RHEL<\/strong>,\u00a0Fedora<\/strong>,\u00a0Debian<\/strong>,\u00a0Ubuntu<\/strong>, etc.).<\/p>\n

In order to clone the target disk you need to physically add a new disk into your machine with at least the same size as source disk used for cloning.<\/p>\n

Requirements<\/h4>\n
    \n
  1. Clonezilla ISO<\/strong>\u00a0image \u2013\u00a0http:\/\/clonezilla.org\/downloads.php<\/a><\/li>\n
  2. New Hard Drive<\/strong>\u00a0\u2013 physically plugged-in into the machine and operational (consult\u00a0BIOS<\/strong>\u00a0for device information)<\/li>\n<\/ol>\n

    How to Clone or Backup CentOS 7 Disk with Clonezilla<\/h3>\n

    1.<\/strong>\u00a0After you download and burn\u00a0Clonezilla ISO<\/strong>\u00a0image to a\u00a0CD\/DVD<\/strong>, place the bootable media into your machine optical drive, reboot the machine and press the specific key (F11<\/strong>,\u00a0F12<\/strong>,\u00a0ESC<\/strong>,\u00a0DEL<\/strong>, etc) in order to instruct the\u00a0BIOS<\/strong>\u00a0to boot from the appropriate optical drive.<\/p>\n

    2.<\/strong>\u00a0The first screen of Clonezilla should appear on your screen. Select the first option,\u00a0Clonezilla live<\/strong>\u00a0and press\u00a0Enter<\/strong>\u00a0key to proceed further.<\/p>\n

    3.<\/strong>\u00a0After the system loads the required components into your machine\u00a0RAM<\/strong>\u00a0a new interactive screen should appear which will ask you to choose your language.<\/p>\n

    Use\u00a0up<\/code>\u00a0or\u00a0down<\/code>\u00a0arrow keys to navigate through language menu and press\u00a0Enter<\/strong>\u00a0key in order to choose your language and move forward.<\/p>\n

    \n

    \"Select<\/a><\/p>\n

    Select Clonezilla Language<\/p>\n<\/div>\n

    4.<\/strong>\u00a0On the next screen you have the option to configure your keyboard. Just press\u00a0Enter<\/strong>\u00a0key at\u00a0Don\u2019t touch keymap<\/strong>\u00a0option to move to the next screen.<\/p>\n

    \"Start<\/a><\/p>\n

    Start Clonezilla for Interactive Menu<\/p>\n<\/div>\n

    6.<\/strong>\u00a0Because in this tutorial we are going to perform a local disk clone, so choose the second option,\u00a0device-device<\/strong>, and press\u00a0Enter<\/strong>\u00a0key again to proceed further.<\/p>\n

    Also, make sure that the new\u00a0hard-dive<\/strong>\u00a0is already physically plugged-in intro your machine and properly detected by your machine.<\/p>\n

    \n

    \"Select<\/a><\/p>\n

    Select Disk to Clone<\/p>\n<\/div>\n

    7.<\/strong>\u00a0On the next screen choose\u00a0Beginner<\/strong>\u00a0mode wizard and press\u00a0Enter<\/strong>\u00a0key to move to the next screen.<\/p>\n

    If the new hard disk is larger than the old one you can choose\u00a0Expert<\/strong>\u00a0mode and select\u00a0-k1<\/code>\u00a0and\u00a0-r<\/code>\u00a0options which will assure that the partitions will be proportionally created in the target disk and the file system will be automatically resized.<\/p>\n

    Be advised to use the\u00a0expert<\/strong>\u00a0mode options with extreme caution.<\/p>\n

    \n

    \"Select<\/a><\/p>\n

    Select Beginner Mode for Disk Cloning<\/p>\n<\/div>\n

    8.<\/strong>\u00a0On the next menu choose\u00a0disk_to_local_disk<\/code>\u00a0option and press\u00a0Enter<\/strong>\u00a0to continue. This option ensures that a full disk clone (MBR, partition table and data) with the same size as the source disk to target disk will be performed further.<\/p>\n

    \n

    \"Select<\/a><\/p>\n

    Select Disk to Local Disk Cloning<\/p>\n<\/div>\n

    9.<\/strong>\u00a0On the next screen you must choose the source disk that will be used for clone. Pay attention at disk names used here. In Linux a disk can be named\u00a0sda<\/strong>,\u00a0sdb<\/strong>\u00a0etc, meaning that\u00a0sda<\/strong>\u00a0is the first disk,\u00a0sdb<\/strong>\u00a0the second and so on.<\/p>\n

    In case you\u2019re not sure what\u2019s your source disk name you can physically examine the source disk name and serial No, check SATA port cabling on the motherboard or consult the BIOS in order to obtain disk information.<\/p>\n

    In this guide we\u2019re using\u00a0Vmare Virtual<\/strong>\u00a0disks for cloning and\u00a0sda<\/strong>\u00a0is the source disk that will be used for cloning. After you successfully identified the source drive press\u00a0Enter<\/strong>\u00a0key in order to move to the next screen.<\/p>\n

    \n

    \"Select<\/a><\/p>\n

    Select Linux Disk to Clone<\/p>\n<\/div>\n

    10.<\/strong>\u00a0Next, select the second disk that will be used as a target for cloning and press\u00a0Enter<\/strong>\u00a0key to continue. Proceed with maximum attention because the cloning process is destructive and will wipe all data from the target disk, including MBR, partition table, data or any boot loader.<\/p>\n

    \n

    \"Choose<\/a><\/p>\n

    Choose Local Disk as Target Cloning<\/p>\n<\/div>\n

    11.<\/strong>\u00a0If you\u2019re sure the source file system is not corrupted you can safely choose\u00a0Skip checking\/reparing source file system<\/strong>\u00a0and press\u00a0Enter<\/strong>\u00a0to continue.<\/p>\n

    Next, the command used for this cloning session will be displayed on your screen and the prompt will wait for you to hit the\u00a0Enter<\/strong>\u00a0key in order to continue.<\/p>\n

    \n

    \"Skip<\/a><\/p>\n

    Skip Checking Source Filesystem<\/p>\n<\/div>\n

    12.<\/strong>\u00a0Before starting the real process of disk cloning, the utility will display some reports concerning its activity and will issue two warning messages.<\/p>\n

    Press\u00a0y<\/code>\u00a0key twice to agree with both warnings and press\u00a0y<\/code>\u00a0key the third time in order to clone the boot loader on the target device.<\/p>\n

    \n

    \"Confirm<\/a><\/p>\n

    Confirm Disk Cloning Warning Messages<\/p>\n<\/div>\n

    13.<\/strong>\u00a0After you agreed all warning the clone process will automatically start. All data from the source drive will be automatically replicated to the target device with no user interference.<\/p>\n

    Clonezilla will display a graphical report regarding all data it transfers from a partition to the other, including the time and speed it takes to transfer data.<\/p>\n

    14.<\/strong>\u00a0After the cloning process finishes successfully a new report will be displayed on your screen and the prompt will ask you whether you would like to use Cloneziila again by entering command line or exit the wizard.<\/p>\n

    Just press\u00a0Enter<\/strong>\u00a0key to move to the new wizard and from there select\u00a0poweroff<\/strong>\u00a0option in order to halt your machine.<\/p>\n

    That\u2019s all! The cloning process is finished and the new hard disk can now be used instead of the old one after it has been physically detached from the machine. If the old hard drive is still in better shape you can store it in a safe location and use it as a backup solution for extreme cases.<\/p>\n

    In case your\u00a0CentOS File System Hierarchy<\/a>\u00a0spawns multiple disks you need to make sure that each disk in the hierarchy is also duplicated in order to backup data in case if one of the disks fails.<\/p>\n
