How To
3-2-1! HAVE A BACKUP STRATEGY FOR YOUR DATA Words by Maribelle Alba

n this digital age, virtually everything important to us is in a mysterious repository inside our laptops or mobile phones.
Translated into real-life, you could have the original copy of your files on your PC, and the second copy on a NAS (Network Attached Storage) in your home network. Finally, the third copy is backed up offsite on cloud storage. For larger enterprises, this could be a disaster recovery site at a remote data center.
Email correspondence, online conversations, social media activity, photos and videos capturing the important moments of our lives — all these are inside some repository on our devices. Have you ever felt the panic of losing a phone? Or that dreadful fear when your PC crashes and you’re unable to access your files? Or even had a ransomware threat?

Once started, you need to do regular and continuous maintenance to ensure that all copies are the same updated versions.
