Is it necessary to backup USB to Dropbox?

Actually, it is necessary for users to backup USB to Dropbox for 2 main reasons: data security and easier access. According to the 3-2-1 backup strategy, you are suggested to make 3 copies of your data and keep at least one copy offsite. As popular cloud storage that can keep your data securely and remotely, Dropbox is a good backup destination for your USB data.

In addition, Dropbox offers different apps for different devices to help users upload and access their files at any time. So, data stored in Dropbox can be accessed more easily than stored on a USB drive. So, many users want to back USB data to Dropbox so that they can access data anywhere without the need to carry a USB.

How to backup USB data to Dropbox?

The above are the two main reasons for backing up USB data to Dropbox. No matter what reason you backing up USB data to Dropbox for, you must need the specific methods to achieve that, please keep reading and find the detailed methods here.

Generally, when you connect the USB drive to the computer, it will be treated as a regular part of your local storage. So, you just need to back up the USB data in the way you usually back up files from local to the cloud. What’s more, both the methods below require you to connect the USB drive to the computer. Please connect it to the computer in advance and read on.

Method 1. Manually backup files on USB to Dropbox

Generally, you can backup files to Dropbox in two ways. The first way is to upload files through the Dropbox web app and the second way is to use the Dropbox folder. The file size that you upload via the first way is limited to 20 GB, but there is no limitation on the second way.

If you use the web app to upload files, you need to select your files manually. And if you want to use the Dropbox folder, you need to download and install the desktop app first and then drag and drop files into the Dropbox folder. So, although the Dropbox folder can sync your files to Dropbox automatically, it also needs many manual operations.

Via Dropbox website:

1. Go to the Dropbox website and sign in to your account.

Log In Dropbox

2. On the Dropbox main page, click the Upload files or Upload folders option to upload your files manually.

Via Dropbox folder:

Method 2. Automatically sync files on USB to Dropbox

Although the manual way above can help you back up files to Dropbox, it may waste much time if there are so many files that you need to backup. Because you can only upload one folder at a time and the transmission process will also take a long time. So, you can turn to an automatic way that can save your backup time and effort.
