The backup purposes are that data loss and corruption can happen anytime to any computer. Or you can choose to clone a small USB drive to a larger one. When you run out of disk storage space on your hard drives, clone the data to a larger drive to use the extra disk space without any data loss. Replacing the old disk with a new one minimizes hard disk failures and maintains your computer at its best performance. Usually, after a few years of use, a hard drive’s firmware will start being outdated and the disk drive itself will start to wear out.
