The significance of Data Backup?

How to backup and save your dataBy data backup we mean the creation of a safety copy of files and folders that are usually kept inside a database, physical or virtual. It is about a real "copy and paste" than what is on the physical memory of the computer, smartphone or tablet that is saved in a different place from the memory of the device itself.

The secondary database can be physical or digital. In the first case, it can be an external hard drive, a USB key or even another computer. In the case of a virtual database, on the other hand, we rely on cloud-type storage which therefore uses the internet connection to store data on an online server.

Why make a backup save?

Usually this type of backup is done for two main purposes:

  • Recover data in case of loss or damage. This process serves to protect important files from digital threats so that they can be restored in the event of an accident or simple system maintenance. Anomalies, failures, errors, thefts, viruses are just some examples of threats that can irreparably damage your files. Among these we cannot fail to mention type viruses ransomware more and more widespread. This type of virus works by blocking all documents on the computer or devices connected to it. It is often impossible to unlock them, except by paying a monetary ransom requested by the hacker
  • Retrieve data before a major change. This case applies to recovering an earlier version of a program or document than the current one. It is usually carried out before delicate operations or operations that require a clear vision of the “before and after” intervention or, if necessary, restore the situation to the moment before the intervention.

For these reasons it is necessary to periodically back up all the data considered critical or vulnerable. It is a tedious and time-consuming procedure (depending on the amount of information) but it represents a lifeline for companies and individuals.
