Do I need backups?

Yes – of your website(s), databases, email & correspondence, accounts etc. and they need to be securely stored separately to the website, and be checked regularly (including carrying out a full restore/rebuild from those backups if possible). Backups are one essential part of Business Continuity Planning, also referred to as Disaster Recovery.
