Why you need a cloud backup service, and how to use one

Cloud backup is the best choice for you to protect your important files in your device. Here’s how to choose a suitable one and use it.


We can understand Cloud backup like it’s name. Your data is stored in an online data warehouse, where you can access whenever you need it. The way it works is like this: You download a desktop client to your PC, and select the folders of data you want to back up, and then the data will be uploaded to the service on the process. Then if have any incident, you lost the data, then up-to-date copy of your data stashed on a server somewhere, all are in safety

Finding a service is easy enough, too. There’s Backblaze (the service I currently use), Carbonite (a service I have used), Mozy, SpiderOak (another service I’ve used), and many others.

The hard problem is understanding how to use cloud backup sevice and acquainted yourself with some problems you don’t ever think of.

Cloud backup vs. cloud syncing

Clarifying the difference between a cloud backup service and a sync service like Dropbox or Google Drive is very important. If you want to sync the data among multiple PCs or mobile devices, you better choose a sync service.

Most mainstream cloud storage backup services offer what’s essentially unlimited backup, though limits of some sort will apply except SpiderOak, which sets data storage limits but offers a higher degree of encryption and security than most services. Skip any cheap service that limits your data to 500GB or 1TB.

It takes time to find out the best solution for your backup service. In general, online backup services help you to protect data in your PC. Some services also let you back up connected drives in total price, but some suppliers charge for it.

Use encryption—and keep the key

Cloud backup services typically encrypt your data in transit and then encrypt it on their servers. That’s a good start, but most services also offer you the option to encrypt your data using your own key (a password).

In case you lock down the data with extra encryption, and you are the only people can decrypt your data should it fall into the hands of hacker or law enforcement. The downside is that if you lose the password to decrypt your data, you’ll lose your backup and have to start all over again. In my opinion, the best way is encrypt and save your password in order to avoid getting lost

The above are problems you need to consider when you want to use cloud storage. Note that your first time backup will take a long time than the others, it’s about one week. And remember, even with a cloud backup you should still maintain a physical, local backup of your data using an external hard drive.
