Servers fail. Hackers compromise your account and delete all your files. Regrettably, computers are vulnerable to hard drive crashes, thefts and virus attacks that could delete all your files. You could lose a lot of stuff like legal and financial documents, email,digital photos and more. This is when a back up service comes in handy.

When enabled, a back up service automatically backs up your files on a daily basis. So if your website or other files are accidentally deleted, you could always download your most recent backup. This backup file will help restore any file that you have deleted or misplaced.

Ideally, your web host shoud be able to provide you with a 24-hour back up facility.
