Now insert the USB flash drive into the port of the computer, copy the received command from the text editor, enter into the terminal and execute (press Enter): The easiest way to create a command is in a text editor. Copy it without quotes and paste it into the command, and in the terminal press the keyboard shortcut ctrl+c to reset and display a new prompt string. The terminal will display the path to the file and the. To correctly enter the path to the file in the command, open the folder with the file, open the nearby terminal and drag the file into it: To identify your flash drive, run in a terminal:Īnd if your flash drive is defined differently, change it in the command. Sdb at the end of the command, this is the flash drive on which the image will be written.

iso you need to specify the path to the iso file from your folder Downloads. The terminal command for writing the iso image of the distribution is as follows: So, suppose you have downloaded an ISO file with a distribution image and prepared a flash drive. Thus, the volume of a disk image created with dd will be equal to the volume of the disk itself - regardless of how much data is on the disk. Special programs can only copy data that is stored on the disk.

dd is a free and very flexible tool, but it can only do a full copy of a volume. kill -USR1 dd_process_number - show copy statistics.Įverything has pros and cons.watch -n 5 - run the command every 5 seconds.Periodically send this process a kill -USR1 dd_process_number command. It is enough to connect to another terminal.ĭetermine the process number under which dd is running. However, this disadvantage can be easily circumvented.

The main disadvantage in dd is the lack of a visual representation of the statistics of the execution of the copy procedure. It should be marked and formatted according to existing requirements. Provided that the new hard drive is larger than the old one, it will remain unallocated area.

Then, if necessary, install the boot from this hard drive. To migrate the entire system to another hard drive, you must set the destination of the new drive as the destination.ĭd if=/dev/sda of=/dev/sdb bs=8M conv=sync,noerror Gunzip -c /mnt/backup/sda.img | dd of=/dev/sda conv=sync,noerror bs=8M Migrating the system to another hard drive When using compression in parallel, you must unzip the image. To restore a hard disk image, you need to follow the procedure reverse to the procedure for creating this image.ĭd if=/mnt/backup/sda.img of=/dev/sda bs=8M conv=sync,noerror To reduce the size of a hard disk image, you can compress it with any archiver.ĭd if=/dev/sda bs=8M conv=sync,noerror | gzip -c > /mnt/backup/sda.img Restoring a hard drive image

conv=sync,noerror - tell dd to copy bit-for-bit, ignoring read errors.

bs=8M - set the size of the hard disk cache to speed up the copy procedure (otherwise the data will be dumped in small portions of 512 bytes).

of=/mnt/backup/sda.img - copy to /mnt/backup/sda.img.

if=/dev/sda - copy the entire hard disk sda.

Create a hard drive imageĭd if=/dev/sda of=/mnt/backup/sda.img bs=8M conv=sync,noerror Mount the hard drive on which you want to save the image. The first step is to boot from any available Live-CD that has the dd utility and log into the command line as superuser. Substitute your own values if necessary.

/dev/sdb is the disk where the image will be written to.

Its purpose is to read data from one device or file and write to another.ĭd can be effectively used to create a hard disk image, while doing without commercial utilities like Acronis True Image or Norton Ghost. Dd- a simple utility that is included with most Unix-like operating systems - Linux, FreeBSD, Solaris, etc.
