This article is about how to use Clonezilla to simplify disk cloning of Linux servers. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Use Clonezilla

There are two versions of Clonezilla, Clonezilla live (installation-free version) and Clonezilla SE (server version). The server version can clone more than 40 computers at a time. Clonezilla live is a stand-alone backup and restore. It works through CD/DVD, USB flash drives, or hardware drivers. The idea, posted on Clonezilla live Media, shows all disk cloning operations by answering a series of questions. To complete a large number of cloning operations, Clonezilla SE requires a DRBL server

Once the system is started, a series of menu screens are displayed in front of you, allowing you to choose how you want to proceed. Two basic operations of Clonezilla are device-to-image and device-to-device. For large-scale image cloning, you may want to make a master disk image first, and then use that image to generate clones. For stand-alone disk cloning, it is better to select device-to-device.

Select the device-to-image option, and you need to answer another set of questions before you begin. In essence, you must specify where the image will be saved in the initial step and where the image will be read out later. Clonezilla supports a wide range of options, including local devices, SSH servers, SAMBA servers, or NFS servers.

Once the device is specified, you must choose the way you want to save or recover the data on the hardware device. Options include saving and restoring entire disks or individual parts.

Clonezilla uses the open source tool Partclone to complete the actual physical cloning of a single disk portion. Partclone is a partition cloning tool that supports many disk formats, including Ext2, Ext3 and Ext4, Reiserfs (file system), Reiser4 and XFS based on Linux, NTFS and FAT based on Windows systems, HFS Plus based on Mac OS X, UFS2 based on BSD Linux, and VMFS format of VMware used in ESX servers.

The process of cloning from disk to disk is simpler. Once you select this option, Clonezilla will prompt the source, followed by the target disk. It will ask you several times if you are really sure to shut down its work before starting. It's a good idea to learn about your hard drive by manufacturer and model, just like the way Clonezilla will present them to you.

This process involves copying the boot sector of the target drive. In most cases, you need to copy the boot sector (master boot record or MBR) because without it, you will not be able to boot the disk. In some cases, you may be prompted not to copy MBR, so they provide this option. There is also a tool called DRBL-winroll that adjusts the Windows system identification number (SID). It can also adjust the Windows hostname, workgroup name, and so on. If you use this tool to move out of the Windows system, this will be very convenient.

Performance can vary widely, depending on the device you use to store the image. Disk-to-disk cloning should be performed at about 50% of the drive rating. This is tantamount to making a typical SATA drive work at 1.5GB per second. I use a high-end AMD quad-core processor, which averages 1.58GB per second.

To address the need for disk cloning, Clonezilla is definitely a tool worth considering. Although it does this based on other open source tools, it integrates these tools into a single boot image, simplifying the process and improving efficiency.
