Back up your data! There are several destructive malware strains circulating that have one main goal, to destroy your data. So, backing up your data weekly or at a minimum monthly is the key to not losing your important Documents, Pictures, Movie files and much more.
Backing up to a cloud backup drive or even a local external drive can save you a lot of frustration! It only takes a few minutes to do, however recovering data is expensive and is not guaranteed.
Backup drives like the ones listed below and your built in Windows or Apple Backup apps are not hard to configure. A few minutes to setup a backup is much better than many hours to recover lost data.
