Have you backed up your data recently? Every day people, businesses, even games lose huge amounts of valuable data because they fail to follow this one basic procedure. World Backup Day is set aside as a reminder to back up your files, even if it’s once a year! A backup is a reserve copy of all the files you’d be loathe to use. There’s nothing more traumatizing than having losing your phone, or having your hard drive crash, and having hundreds of valuable and irreplaceable documents or photos suddenly gone beyond retrieval.
