Technologies can fail at the most unexpected moment — many people have found themselves in a situation where several hours of their work were wasted due to the fact that the data was not saved. An even worse case is the loss of all files on your computer, smartphone or tablet. However, you can fix this by creating a backup copy of the data, that is, a backup copy of all files on this disk.
What is a backup?
As mentioned in the introduction, this is done to protect data from accidental destruction caused by various factors, such as viruses, damage to the system or disk partition, or the entire computer, and even accidental deletion of necessary files. There are many reasons for data destruction, and the easiest and fastest protection is usually a backup.
This is the most frequently saved system image along with all the files saved on the device during backup. It also happens that the concept of backup does not include an operating system image, but copies of the designated files.
How do I back up my data?
This is a very individual issue - some prefer to leave the entire process in the hands of the system they work on, others create their own backups, transferring them to external media, and others automate the process according to their needs.
In the case of systems such as macOS, Linux or Windows, they already have a built-in module that will guide the user through all the steps of data backup. This is usually a safe option, although not quite.
The operating system saves the system image to the disk of a computer or smartphone, updating it by itself at specified intervals, and all you have to do is set how often the new backup should overwrite the old one. It's the same with phones and tablets — almost every version of Android and all versions of iOS have the ability to back up data. The problem occurs when the disk to which it is written is mechanically damaged.
