Each year there are stories of people who have lost all of their sequencing work (and family photos) because of a hard drive crash or other disaster. If they had a backup of the data, then restoring it would be easy.
However many people today do not have a backup solution and are at risk of losing their data. Imagine that you go home to find your house burned to the ground. Nothing left. Suppose severe weather hits and knocks your house down, and your locally stored backups are flung to some remote place never to be seen again. Or the worst case, your home is burglarized and and all of your computer equipment is taken. Would you be able to recover your data if this were to happen to you?
By now you see it's possible to lose data in a number of ways. You need to backup your data in a way that is safe and reliable.
