I wonder: Why UNIX programming community is unable to develop a disk copy tool of superior functionality, such as one have on OpenVMS. Today I copied Seagate 72 GB Linux system disk to 72 GB HP disk again using dd:ĭd if=/dev/sdc of=/dev/sdd and got a message:ĭd:writing to ‘/dev/sdd’: No space left on deviceĪgain there is a problem of a smaller disk! And what about partition boundaries and partition table? Clonezilla is also reported not to support copy to a smaller disk. When I wanted to make a full copy of Linux system (bootable) disk from Fujitsu 18 GB disk to Seagate 18 GB disk using dd, I got a message at the end of the process that the last 100 sectors were not copied because the Seagate disk was full.ĭid I lost some important data, or there were just empty sectors, I do not know.

Redo backup and recovery software in action This increases the clone efficiency.įig.04. Clonezilla saves and restores only used blocks in the harddisk. Clonezilla server edition – Use this at office or data center for massive deployment, it can clone many (40 plus!) computers simultaneously.Clonezilla live – Use this at home or for single machine backup and restore.Clonezilla works in any one of the following mode: This software allows you to do bare metal backup and recovery. If you are looking to replace Norton Ghost Corporate Edition, try Clonezilla. You need to install partimage-server package which provides server daemon for remote imaging, much like Ghost. This provides the ability to perform an hard disk partition recovery after a disk crash. Partitions can be saved across the network using the partimage network support, or using Samba / NFS (Network File Systems). Since the partition is processed on a sequential sector basis disk transfer time is maximized and seek time is minimized. This is done for speed and efficiency, free blocks are not written to the image file. Please note that partimage will only copy data from the used partition of the partition. You can use it with FreeBSD / OpenBSD / Mac OS X / MS-Windows and so on: The dd command can make backup of any partition regardless of an operating system. # dd if=/nfs/backup/images/backup.sda1.07.28.12.img of=/dev/sda1 bs=1M conv=noerror # dd if=/dev/sda1 of=/nfs/backup/images/backup.sda1.07.28.12.img bs=1M conv=noerror You can duplicate a disk partition called /dev/sda1 as a disk image file called .dd.yy.img file: # dd if=/dev/sdc of=/dev/sdd bs=1M conv=noerror You can clone a hard disk /dev/sdc to /dev/sdd: # dd if=/dev/sdb3 of=/dev/sdc3 bs=4096 conv=noerror To clone /dev/sdb3 partition to another partition called /dev/sdc3, enter: It can also be used for backing up the boot sector (MBR) of a hard drive or destroy data using /dev/zero or /dev/random. It copies the standard input to the standard output. The dd command allows you to make the low-level copying and conversion of data in raw format.
