It is very important to have clones, copies or backups of your data and it should be easy accessible for recovery. Without a clone or backup, usually you need to install the operating system (Windows, Linux, MacOS) from scratch and then all your programs and also to make the correct settings (usernames, passwords etc…) for the programs to work correct. This process will take a lot of time. But if you have a clone, it will be an easy process to recover everything.
Disk cloning is the process of creating a 1-to-1 copy of a hard disk drive (HDD) or solid-state drive (SSD), not just its files. Disk cloning may be used for upgrading a disk or replacing an aging disk with a fresh one. In this case, the clone can replace the original disk in its host computer. Disk cloning may also be used for disaster recovery or forensics.
