The dd utility on a Linux boot CD can be used to copy file systems between disk images and disk partitions to effect a bare-metal backup and recovery. These disk images can then be used as input to a new partition of the same type but equal or larger size, or alternatively a variety of virtualization technologies as they often represent a more accessible but less efficient representation of ...
Redo Rescue, formerly Redo Backup and Recovery, is a free backup and disaster recovery software. It runs from a live CD, a bootable Linux CD image, features a GUI that is a front end to the Partclone command line utility, and is capable of bare-metal backup and recovery of disk partitions. It can use external hard drives and network shares.
Partclone is a partition image tool which attempts to only back up used data blocks. It's written in C and focuses on cloning filesystems, as opposed to cloning disks. The basic features are: clone partition to image file; restore image file to partition; restore image file to raw file as loop device; duplicate partition on the fly
The most common data recovery scenarios involve an operating system failure, malfunction of a storage device, logical failure of storage devices, accidental damage or deletion, etc. (typically, on a single-drive, single-partition, single-OS system), in which case the ultimate goal is simply to copy all important files from the damaged media to another new drive.
shred is a command on Unix-like operating systems that can be used to securely delete files and devices so that it is extremely difficult to recover them, even with specialized hardware and technology; assuming recovery is possible at all, which is not always the case.
dd is a command-line utility for Unix, Plan 9, Inferno, and Unix-like operating systems and beyond, the primary purpose of which is to convert and copy files. [1] On Unix, device drivers for hardware (such as hard disk drives) and special device files (such as /dev/zero and /dev/random) appear in the file system just like normal files; dd can also read and/or write from/to these files ...
Figure 1: An illustration of connecting two drives to a computer to clone one drive (the source drive) to another (the destination) drive. Disk cloning occurs by copying the contents of a drive called the source drive. While called "disk cloning", any type of storage medium that connects to the computer via USB, NVMe or SATA can be cloned. A ...
Disk cloning software facilitates a disk cloning operation by using software techniques to copy data from a source to a destination drive or to a disk image. List [ edit ]
