The easiest way to back up a Windows computer to the cloud is the built-in Windows Backup app: type “backup” in Start, open Windows Backup, sign in with a personal Microsoft account and choose the folders to send to OneDrive. A free Microsoft account includes 5 GB of OneDrive storage, so larger backups need a paid plan or a dedicated service such as CBackup or Backblaze.
Key Takeaways
- Windows Backup, built into Windows 11 and Windows 10, backs up the Desktop, Documents, Pictures, Videos and Music folders plus settings and apps to OneDrive.
- Free cloud storage is small: 5 GB with a Microsoft account, 15 GB shared across a Google account and 2 GB with Dropbox Basic, as of October 2026.
- CBackup, covered step by step below, is a free Windows backup tool with paid plans from $3.99 per month as of October 2026.
- Follow the 3-2-1 rule: three copies of your data, on two different media, with one copy off-site, such as in the cloud.
- A backup is only useful if it restores, so test a restore after setting one up.
A figure often repeated online says nearly 80% of users have experienced computer crashes and breakdowns; no primary source for that number could be found, but hardware failure, theft, accidental deletion and ransomware are all common causes of lost files. For non-technical users, it is difficult to solve these problems, even some users choose to abandon all files and restart the new system. But in this case, all important photos, documents, slides, etc. on the computer will be lost.
To prevent accidental data loss, it is best for computer users to always back up files. This article explains the easiest ways to back up computer files to the cloud, with step-by-step instructions for each.

Why do you need to backup computer to the cloud?
There are two mainstream backup methods. One is to back up computer files to the cloud, and the other is to back up data to external hard drives or USB. If you use an external hard drive, the risk of loss or theft is still great.
If an accident happens, important data will be lost permanently. In this way, you should not ignore the importance of cloud backup.
You can consider backing up PC files to the cloud from the following points.
Safer backup destination
Unlike traditional backup methods, using cloud backup services can transfer important data to a remote server, which is what we call cloud. Data stored in the cloud is kept away from your home or office, so a local fire, flood, theft or drive failure does not destroy that copy as well.
Flexible storage
Traditional backup technology only allows users to back up data to devices with fixed and limited capacity. The cloud-based backup can expand the storage capacity, and users can subscribe to different specifications of backup plans according to the data demand and the number of users.
Reliable disaster recovery
Backing up data to the cloud usually requires professional cloud backup services, which can provide users with instant access to important data on applications in the event of natural disasters or human error. And when you lose a file locally, you can quickly restore the backup file from the cloud server.
How to backup PC to cloud with CBackup?
In the digital age, backing up data to the cloud has become crucial. But you may not know how cloud backup works. For important data, choose a reliable service. CBackup is one option, and its steps are shown below; the built-in Windows Backup app and other services are compared later in this article.
CBackup
CBackup is a Windows backup and sync tool whose basic version is free to download. When this article was first published in 2021, CBackup let users back up a Windows PC to its own cloud and gave each account 10GB of free CBackup Cloud space; as of October 2026 the official pricing page lists CBackup Cloud as a paid plan with 1TB of storage, so check the current free allowance before relying on it.
And it allows users to back up files to mainstream cloud storage services, such as Google Drive, OneDrive, Dropbox, etc. If you prefer to keep backups in a cloud drive you already use, CBackup can send them there instead of to its own cloud.
CBackup also supports various useful functions to provide users with comprehensive and professional PC cloud backup and restore strategies. Scheduled backup, file filter, email notifications, data restoration, etc. can improve the user’s backup efficiency and make the backup process easier.
CBackup offers a free version. As of October 2026, its official pricing page lists CBackup Professional at $3.99 per month (billed $47.88 a year) and CBackup Cloud with 1TB of storage at $7.99 per month (billed $95.88 a year); whether that is the best value depends on how much data you need to protect.
Backup computer files to CBackup Cloud with CBackup
Step 1. After downloading and installing CBackup to your computer, launch the application and create an account, log in to start using it.
Step 2. Click the Backup Tasks option in the task bar on the left, and then click New Task to create a cloud backup task.

Step 3. You can change the Task Name to distinguish different tasks later. Click the Add Source button, you can select the disk or folder in it to be backed up.

Step 4. Click Add Destination and select CBackup Cloud as the backup destination.
Step 5. Click Start Backup to confirm that the task can be started.
Backup computer files to Cloud drives with CBackup
Step 1. Log in to the application with your CBackup account.
Step 2. Click the My Storage option in the task bar on the left, click the (+) button > Add Cloud. Then select the cloud storage service you need to add, and click Add to confirm. You only need to authorize CBackup to access the files in your cloud drive account according to the following instructions.

Note: CBackup says it connects to cloud drives through OAuth and encrypts data in transit with 256-bit AES. As with any backup tool, also protect the cloud account itself with a strong password and two-step verification.
Step 3. Then go to Backup Tasks > New Task.

Step 4. Click the Add Source button and select the files on the local computer that need to be backed up, and click Add Destination to select the cloud drive you need to back up to (If you add different accounts under the same service to CBackup, you’d better make sure that the backup is to the correct account).

Step 5. Finally, click the Start Backup button.

Note: If you want to use more backup functions, you can click Settings in the lower left corner of the screen to set before starting the task.
Final Words
Cloud backup has become an important part of protecting work and study files. Following the steps above, CBackup is one way to back up PC files to the cloud; Windows Backup with OneDrive and dedicated services such as Backblaze are alternatives covered in the sections below.
How Do You Back Up a PC to the Cloud With Windows Backup?
Windows Backup is Microsoft’s built-in backup app for Windows 11 and Windows 10. According to Microsoft Support, it backs up the Desktop, Documents, Pictures, Videos and Music folders, installed apps, Windows settings, and accounts, Wi-Fi networks and passwords, and it stores the folder backups in OneDrive. Microsoft notes that support for Windows 10 ended on October 14, 2025.
- Select Start, type backup and choose Windows Backup from the results (or open Settings > Accounts > Windows backup).
- Sign in with a personal Microsoft account such as an outlook.com or live.com address; Microsoft says work and school accounts are not supported.
- Choose which folders to back up to OneDrive and whether to include settings and apps.
- Start the backup and let the first upload finish while the PC stays online.
- When you sign in to a new PC with the same account, the backed-up folders and settings can be restored.
A free Microsoft account includes 5 GB of OneDrive storage, which fills quickly with photos and videos, so most people with large libraries need more space or a separate backup service.
Which Cloud Backup Option Should You Choose?
The right cloud backup option depends on how much data you have and whether you want simple folder backup or a full-PC backup. The table below summarizes plans as listed on each provider’s official pages, as of October 2026.
| Option | Free storage | Paid option (as of October 2026) | Best for |
|---|---|---|---|
| Windows Backup + OneDrive | 5 GB with a Microsoft account | Microsoft 365 / OneDrive plans | Simple folder and settings backup on Windows |
| Google account (Drive) | 15 GB shared across Gmail, Drive and Photos | Google One membership | People already using Gmail and Google Photos |
| Dropbox Basic | 2 GB, up to 3 devices | Higher Dropbox plans | Small sets of documents; Dropbox can back up computer files |
| CBackup | Free Windows software; check current cloud allowance | Professional $3.99/month; Cloud (1TB) $7.99/month, billed yearly | Scheduled backups to its own cloud or to Google Drive, OneDrive and Dropbox |
| Backblaze Personal Backup | None | $99 per year, unlimited data backup | Large libraries and whole-computer backup |
Prices and allowances change often, so confirm the current figures on each provider’s site before you subscribe. If you are moving files between services, see this guide on transferring files from Dropbox to Google Drive.
What Is the 3-2-1 Backup Rule?
The 3-2-1 backup rule means keeping three copies of your data on two different media with one copy off-site. Backblaze describes it as the original data plus two copies, stored on separate types of storage, with one copy in a remote location. A practical home setup is the files on your PC, a copy on an external hard drive, and a copy in a cloud backup service.
Cloud backup covers the off-site part of the rule, while an external drive gives fast local restores. Using both protects against a failed drive and against theft, fire or flood. For more on why off-site copies matter, read why it is important to back up and recover data in the cloud.
Is Cloud Sync the Same as Cloud Backup?
Cloud sync is not the same as cloud backup. A sync service mirrors changes, so if a file is deleted, overwritten or encrypted on the PC, the change can be copied to the cloud as well. A backup keeps separate copies, often with versions, so older files can be restored.
This difference matters most with ransomware, which encrypts files on a computer; a backup that keeps earlier versions or is stored separately gives a way to recover. Learn more about common types of ransomware.
Common Cloud Backup Mistakes to Avoid
- Never testing a restore: restore one or two files after setup to confirm the backup works.
- Running out of free space: free tiers of 2 GB to 15 GB fill up, and a full account stops accepting new backups.
- Backing up only some folders: check that files saved outside Desktop, Documents and Pictures are included.
- Weak account security: anyone with the cloud account password can reach the backup, so use two-step verification.
- Relying on one copy: keep a second copy on an external drive, following the 3-2-1 rule.
CBackup’s interface has also changed since 2021; its download page lists version 3.0.0, updated on August 28, 2025, so menu names may differ slightly from the screenshots above. For a wider comparison of tools, see the top backup software for Windows PCs, and if files are already lost, a file recovery tool may help.
