What is cloud backup?

Before talking about cloud backup, let’s get the basics. In the past, many users always back up data to local disk or external drive, which is very convenient for a quick restoration. But it often makes us suffer from fire, stolen, or other local disaster like system failure.

Therefore, people invented PC cloud backup and successfully attracted everyone’s attention. Because it claims to be a service that can backup main data storage systems, remote office servers and storage devices, end-user devices such as laptops and tablets, and store the files on a remote server off-site to avoid nature and local disasters.

Always be prepared - local backup vs PC online backup

After a period of use, your personal PC would end up having lots of data of yours, such as, personal documents, photos, videos, and any other data. It’s wise to make a copy of your important files. More importantly, you are supposed to create a continuous or schedule backup. Because just making a single backup won’t give you the latest version of your files when you need to restore.

With a local backup, your PC may get damaged or stolen, the ransomware can prevent you from accessing your data, or any human error and occasional disaster can make you lose data. But if you use online computer backup as instead, you can greatly reduce these risks.

If your budget is limited and you can only choose one of the backup methods on the market, your best choice is online PC backup software and I’ll introduce you best online computer backup service and its features. But if you have more budget, you can backup computer files online, and to internal disk, external hard drive, or USB flash drive etc.
