Hard drive failure is one of the most disastrous things that can occur on your system that is only made worse, if you have no backup plan in place. To keep your data safe, all you need to do is either utilise cloud storage or purchase another hard drive, whether internal or external. Alternatively you could go with a flash drive, if you intend to backup only smaller documents.
When you have your backup system in place, it should carry out regular backups on your behalf, providing it has enough storage space to do so.
