181:, is to boot from a Linux-based operating system so the drive can be copied and/or overwritten. This approach is not suitable for servers that need to be running all the time and cannot be shutdown routinely to perform the backup (or cloning) operation. Further, the Linux-based operating system must provide appropriate drivers for the system's hardware. Drivers are also required for the source and destination drives and for any attached storage involved in facilitating the cloning operation such as USB, tape device and networking drivers.

exclude unwanted data from being duplicated reducing cloning time. For example, the filesystem and partitions can be resized by the software allowing data to be cloned to a drive equal to or greater than the total used space. Most hardware-based cloners typically require for the destination drive to be the same size as the source drive even if only a fraction of the space is used. Some hardware cloners can clone only the used space but tend to be much more expensive.

process itself must not interfere with the data. Because software cannot be installed on the system, a hardware-based cloner is generally used to duplicate the data to another drive or image. Further, the hardware-based cloner also has write-blocking capabilities which intercepts write commands to prevent data being written to the drive.
200:
Disk cloning can be time consuming, especially, for large disks because a true clone needs to copy all the data on the disk even if most data resides in unallocated drive space. Software solutions can determine the space in use and only copy the used data reducing the time needed to clone the drive.
115:
One of the most common applications of disk cloning is for digital forensics purposes. This aims to ensure that data is preserved at the time it was acquired for later analysis. Techniques for cloning a disk for forensic purposes differ from cloning a drive for other purposes. Typically, the cloning

A common use of disk cloning is for deployment. For example, a group of computers with similar hardware can be set up much quicker by cloning the configuration. In educational institutions, students are typically expected to experiment with computers to learn. Disk cloning can be used to help keep

Upgrading to a larger or faster drive can be facilitated by cloning the old drive to the new drive once it is installed into the system. This reduces the need to having to manually reinstall applications, drivers and the operating system. The procedure can be used when migrating from mechanical

Typically, the destination drive is connected to a computer (Fig. 1). Once connected, a disk cloner is used to perform the clone itself. A hardware-based drive cloner can be used which does not require a computer. However, software cloners tend to allow for greater flexibility because they can

Disk cloning can be used as a backup solution by creating a duplicate of data as it existed when the clone was started. The clone can be used to restore corrupted files such as corrupted databases. In modern software solutions, it is not uncommon for disk cloning techniques to be combined with

174:. Consequently, the drive cloner must ensure that the data on the source drive remains in a consistent state at the time of reading. 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.
146:. Modern cloning software tends to communicate with storage devices through a common interface, which means, that any storage device can be cloned and migrated. Sometimes, booting from the destination drive can fail and require adjustments in the computer's

192:(VSS). VSS takes a snapshot of the drive so that any changes are not written to the snapshot. The snapshot creates a virtual drive called a shadow volume that is backed up (or cloned) by the software.
