What is the best storage device for your backup?

To create a backup is very essential. With a backup, you can avoid data loss to the maximum extent. And there is a question you cannot ignore: what is the best storage device for your backup?

Many users will choose to buy an extra external hard drive, USB flash hard drive, NAS, etc. However, I prefer to backup external hard drive to cloud storage device instead of backing up to external hard drive. It offers you a free space without costing you a cent. And there is no risk of hard drive failure, system crash, etc.

What’s more, no matter what happens, you can access your cloud backup on any device anywhere via an internet connection.

Dropbox is one of the most popular cloud storage devices which can protect your backup in a better way. Download Dropbox and try it for yourself.

How to backup data on external hard drive to Dropbox?

Backup software for external hard drive
