In other words, it can clone one disk to another without knowing what partitions or file systems the source disk has. This indiscriminate approach, however, is inefficient because it would mean copying every block, even if it does not contain meaningful data. Therefore, Clonezilla uses a smart file system-aware approach.
Further, in the case, that the user desires to clone to the computer's system drive, this generally cannot be done while the operating system is running. A common solution to cloning a drive that is in use, which is utilized by software such as CloneZilla, is to boot from a Linux-based operating system so the drive can be copied and/or overwritten.

In OS X El Capitan , Disk Utility has a different user interface and lost the abilities to repair permissions due to obsolescence , [ 6 ] create and manage disks formatted as RAID , burn discs, and multi ...
A disk image is a snapshot of a storage device's structure and data typically stored in one or more computer files on another storage device. [1] [2]Traditionally, disk images were bit-by-bit copies of every sector on a hard disk often created for digital forensic purposes, but it is now common to only copy allocated data to reduce storage space.
Clonezilla: a free disk cloning, disk imaging, data recovery, and deployment boot disk; dd: common byte-to-byte cloning tool found on Unix-like systems; ddrescue: an open-source tool similar to dd but with the ability to skip over and subsequently retry bad blocks on failing storage devices
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
EasyBCD has a number of bootloader-related features that can be used to repair and configure the bootloader. From the "Manage Bootloader" section of EasyBCD, it is possible to switch between the BOOTMGR bootloader (used since Windows Vista) and the NTLDR bootloader (used by legacy versions of Windows, from Windows NT to Windows XP) in the MBR from within Windows by simply clicking a button.
