Since your information could be lost or compromised (due to an equipment malfunction, an error, or virus), make regular backups of your information. There are many cloud services that offer backups, and you can schedule automatic backups.
Backups also help you identify what has been changed or lost. If your computer has been infected, it is important to remove the infection before resuming your work. Save some older backups, because if your computer gets infected, some of your backups may also be compromised.
