My design professors always stressed saving and backing up our work often, if not compulsively. Luckily, I took heed of their warnings and never had a major stress inducing incident causing many lost hours of sleep and damaged grades. Although after my backup external hard drive was damaged and corrupted, losing megabytes of files, my laptop was then my backup. In a horrible hypothetical situation which both would have been corrupted, all of my work would have been lost.
Finding an alternative mode of back up other than physical copies, online cloud services offer just another great safety net. Uploading important files will protect them from physical damage while still having a hard drive safe from any type of online loss of data. Instead of a anxiety attack and injured grades, loss of important files in the work world can lead to loss of money, business, and reputation.
