Instead, online backup systems can only effectively backup your data. I’d like to emphasize this, due to technical limitations beyond the control of online backup companies they are not able to backup everything on your Mac, the way Time Machine is able to do. Backblaze, or any, online backup system creates an off-site backup of your data like emails, photos, music, calendar, etc. More specifically, initially setup the Time Machine backup application and then supplement it with an online backup service like Backblaze or CrashPlan (or at least create a second Time Machine backup stored on a second, off-site hard drive). What should you do to protect yourself? Set up redundant, automated backup systems that produce multiple backup copies of your files in multiple places. Most of these problems have occurred to at least one of my clients within the past year! Every one of these situations has occurred to one or more of my clients.

Why? Because you never knows when disaster will strike and you’ll need to rely on a recent backup to retrieve one or many files. Everybody should backup all files on their Mac’s hard drive every day. They also ask me which files they should backup. Clients often ask me how often they should backup their Mac.
