About Online Backup

Online backup means using a network connection to back up data from a computer or hard drives to a remote server (that is the cloud storage service we generally mentioned). Online backup services usually provide a web-based management console to access data and monitor the running status of backups. The backed-up files will be encrypted and stored in the provider's data center. Individuals or businesses can directly download and use data backup or browse archived files from any computer or device.

Why Use Online Backup to Protect Your PC files?

Nowadays, users and enterprises of any size more and more rely on this kind of online backup because it has many advantages as below:

Avoid data loss: Data stored in local storage is still at the risk of loss for hardware failure, system crash, and natural disasters. But if you back up your files with online backup, your data will remain safe even when you encounter disasters such as fires, floods, or employee theft.

The initial cost is small: Most online backups do not require you to purchase any hardware and provide a certain amount of free storage or a certain period of a free trial. So, if you only need to backup a few files, you even don’t need to pay any fee.

Universal restore: As mentioned above, online backup allows you to backup and restore files with a Web browser interface or PC client. So, it is very easy for you to transfer files between two devices by doing a universal restore.

When Should You Make Online Backup?

If your computer crashes, is stolen or hacked, or even the mobile hard disk fails, these conditions will cause your data to be lost. This time the importance of online backup is reflected! If you do not prepare countermeasures in advance, you will spend a lot of time and money to retrieve your data. However, as long as there is a good network, you can retrieve your data through free cloud backup.

Online backup ensures that files are copied in the cloud so that you can restore everything back to its original state. Moreover, compared with tape or disk backup, online backup is highly scalable. When your data backup needs become larger, you can expand the storage space by purchasing a subscription plan for backup services.
