But even if you never have to restore a single file, backups can still give you peace of mind. Join Gizmag, as we review Backblaze, a simple and affordable service that backs up your entire PC.

There are two potential problems with backing up your entire PC to the cloud. For starters, it typically takes a long time to upload everything. One PC's hard drive can take a couple of weeks to fully upload – even with a fast internet connection. Then there's also the fact that your most important files are now sitting on some company's remote servers. You'd better pick a service with an eye or three on security.

Backblaze can't do much about the time it takes to upload data, but the service does make the process about as painless as possible. After installing the app, you simply let it run in the background. That's it. Sure, there are a few settings you can tweak if you like, but it really can be as simple as "turn on app, forget about it."
