How to set up local backup without sending data to the cloud?

Question

Accepted Answer

Modern operating systems and applications by default strive to save all backups in cloud storage. This is convenient for recovery, but creates serious risks for privacy, as your files are stored on third-party servers. Organizing a local backup allows you to completely control the process and exclude the transfer of personal information to third-party companies.

To implement this approach, you will need an external hard drive or NAS network storage, as well as specialized open-source software. It is important to choose tools that support local data encryption right on your device before writing them to the media.

The setup process looks like this:
1. Connect the external drive to the computer and format it into a reliable file system.
2. Install a proven backup program with encryption support, such as BorgBackup or Duplicati.
3. Specify the folders and files that require regular saving, excluding temporary system files.
4. Set a strong encryption password and save it in a password manager, as without it, data recovery will be impossible.
5. Set up an automatic backup schedule to run in the background when the target disk is connected.

Regularly check the operability of the created archives by restoring random files to an isolated folder. This approach guarantees that your personal documents, photos, and work projects will remain exclusively under your physical protection, without leaving the confines of your home or office.
