Backup C Drive to OneDrive

"How do I automatically back up my Windows 10 C drive files to Microsoft OneDrive? Some important program files and some pictures are saved in my C drive. Now, I need to back up these files to my OneDrive account. Is there a more practical way to do this? "

Why Backup C Drive to OneDrive?

OneDrive can provide users with a sync and share service, which means that your documents, spreadsheets, music and image files can be stored in OneDrive without damage. As mentioned by the user above, in order to avoid data loss due to hardware failure (such as a disk drive crash), you can directly back up the application and operating system data from the C drive to OneDrive.

In the past, many users liked to install some applications directly on the external hard disk other than C drive, which can greatly reduce the use of computer system storage and use the computer more smoothly. But now, with an excellent cloud storage service like OneDrive, users are more willing to back up C drive data to the cloud because:

  • Lost data can be easily recovered. When storing important data to the cloud, users can get operating system and application-related files directly from OneDrive. So you don't have to worry about hardware failures and natural disasters.
  • Data can be easily accessed and shared. When important photos are in OneDrive, you can access the files remotely from smartphones and tablets. Plus, you can share pictures with your friends and family via email and links.
  • Storage space is easily expandable. You can only buy the rated storage capacity when using an external hard drive to store your data. While, OneDrive offers a variety of storage capacity options, such as 5GB-6TB, and also provides more affordable data plans for business users.

How to Backup C Drive to OneDrive [2 Ways]

There are 2 methods to backup C drive files to OneDrive, you can choose one method to operate. Before doing so, you need to make sure that OneDrive has enough storage space for all the files you want to back up. If 5GB of storage isn't enough, you can buy more storage. Alternatively, you can choose to register multiple accounts to consolidate cloud storage.

Solution 1: Backup User Folder to OneDrive by OneDrive App

One of the easiest ways to back up C drive files to OneDrive is to add its dedicated drive to your system. After you download the OneDrive program on Windows, you can keep important folders on your computer (Desktop, Documents, and Pictures) on OneDrive, so you can protect and access them on other devices.

Step 1: Select the blue cloud icon in the Windows notification area, click the gear icon at the top right of the pop-up window, and select Settings > Manage backup.

Step 2: In the "Manage folder backup" dialog box, you can choose to back up the "Desktop", "Documents", and "Pictures", and then click "Start Backup" to back up the files to OneDrive.

The above method can only support backing up the entire "Desktop", "Pictures", and "Documents" folders to OneDrive. If you want to backup individual files or folders, you can copy them to OneDrive through the Windows file explorer.

Step 1: Open your OneDrive folder in File Explorer.
Step 2: Copy your C drive files to the OneDrive folder, then paste.

Through the above operation steps, you can know that using the OneDrive desktop application to backup C drive files still has certain limitations.

1. C drive files cannot be individually selected for backup. Currently, OneDrive only supports backing up the entire "Desktop", "Pictures", and "Documents" folders, and cannot support you to individually select a file or folder in C drive for backup.
2. A full image of the hard drive cannot be generated. For users who need to back up their computer systems, OneDrive is obviously not suitable because it can not generate a full image of the hard drive, enabling you to perform a full recovery using bootable media. File recovery in OneDrive allows you to download documents, spreadsheets, music and images. 
3. Regular backup is not supported. This may be a common problem with many cloud storage services. OneDrive does not support user-defined backup and sync times, which is still inconvenient for users who need regular backups.

Solution 2: Backup C Drive to Onedrive by Third Party [Scheduled]

Microsoft OneDrive already provides many users with a temporary backup solution for some of the more important files. However, it is by no means a complete backup product. OneDrive only allows you to manually sync files with local devices and OneDrive. You can't have it automatically back up all your files, which means you can't back up anything that isn't a file (applications, user profiles, settings, etc.).

To get around OneDrive's backup limitations, you can use AOMEI Backupper software to create powerful backups that automatically protect your entire computer and save your backups on OneDrive. The entire backup is done automatically, and you don't need to "watch" them or remember to run the backup once it's set up. In addition, this third-party file backup software:

  • Supports Windows 11/10/8.1/8/7/XP/Vista.
  • Supports 4 sync methods, namely Basic Sync, Real-Time Sync, Mirror Sync, Two-Way Sync. The last three methods are available on later versions, such as AOMEI Backupper Professional.
  • Supports daily/weekly/monthly schedule sync.
