Backup your data
Take regular backups of your important data, (it’s probably ALL important), and test that they can be restored. This will reduce the inconvenience of any data loss from theft, fire, other physical damage, or cyberattack.
With regard to ransomware, make sure you have an offline or disconnected backup copy.
Identify what needs to be backed up, it normally comprises documents, photos, emails, contacts and calendars, kept in a few common folders, make backing up part of your everyday business.
Ensure the device backing up your data is not permanently connected to the device holding the original copy, neither physically nor over a local network.
Consider backing up to the cloud, this means your data is stored in a separate location (away from your offices and devices) and you’ll also be able to access it quickly from anywhere.
