How to Back Up Important Files Before a Computer Fails

A simple backup habit that costs almost nothing and saves the files you cannot replace.

The rule that actually works

Keep important files in more than one place, and make sure at least one of those places is not inside the computer. A single copy on the machine is not a backup, no matter how organised it is.

Two practical options

  • An external drive, with your documents and photos copied onto it on a regular schedule you will actually keep.
  • A cloud service that syncs your documents and photos folders automatically, which removes the discipline problem.

Test it once

Open a couple of files directly from the backup. A backup nobody has ever restored from is only a hope. Five minutes of checking now is worth far more than a recovery attempt later, since recovery is never guaranteed.
