Data Backup

We often hear the phrase "Have you backed up?" but most of us neglect to get into the process of keeping copies of our files. "But there comes a time when our cell phone breaks down, our hard drive burns out and some malware corrupts our data. Then it's already too late to save our personal data.

So let's start with the basics.
What is backup?
The term backup or backup refers to the process of copying and archiving data to a different and secure location (secondary location) so that it is easier to restore them in case the original files are lost, deleted, damaged or changed.

Our data can have a different format or features and some of them are photos, files, codes, customer details, tax details etc.

How do we backup?
The simplest and easiest way to make backups is to use cloud storage services: Services like Dropbox, Google Drive, iCloud, Microsoft OneDrive, Amazon Photos (for Prime subscribers) etc., provide you with the capacity to save your important files and access them from any device and computer. For your documents, files, music and video folders, you can use OneDrive or Dropbox.

The most common and traditional way to backup files is to save them on a separate storage medium (eg hard disk, tapes, CD, USB Flash). Caution! Storing your files on the same disk as the original data is not considered backup! It is the most common mistake as if something happens to the original medium, both your original data and the supposed "Backup" that you have are lost.
Automated backup of sensitive data. It is aimed mainly at professionals who have important data and want to protect it from loss due to hardware failure or malicious action. It is done with specialized applications or customade and usually through a network.
In any case, storing your data other than your computer or laptop on a hard drive can be a lifesaver.

Is only one backup enough?
The truth is that no. To make sure your files are always safe it is good to use at least two different ways to keep a backup. There are two ways you can keep backups, the offsite way (Dropbox, cloud, etc.) and the onsite way (external hard drive that is connected to the computer).
