This video discusses how easy it is to lose important data and files and the 3-2-1 backup rule. Various scenarios are presented along with statistics related to data and device loss. This is followed by a discussion on the 3-2-1 backup rule. The 3-2-1 backup rule involves having 3 total copies of your files (1 original + 2 backups) on 2 different mediums (e.g., hard drive, flash drive, cloud, etc.) with at least one of those copies offsite (e.g., cloud storage, friend’s, relative’s, etc.).
Note: This is a combined video of the two shorter ones.
