What is the best PC backup software for Windows 11/10?

Dropbox is a popular cloud storage service that can be used as a free PC backup software for Windows 11/10. It allows you to automatically sync and store your important files and folders in the cloud, making them accessible from any device with internet access. Here's how it works in simple terms:

1. Free Storage Space: Dropbox offers a free plan with a limited amount of storage (usually 2 GB), which is enough for backing up essential documents, photos, and smaller files.

2. Automatic Syncing: You can choose specific folders on your PC to sync with Dropbox. Once set up, any files you save or update in these folders are automatically uploaded to the cloud.

3. Easy Access: Files stored in Dropbox can be accessed from the Dropbox app on your PC, or via their website, so you can retrieve your backups anytime, anywhere.

4. File Versioning: Dropbox keeps previous versions of your files for a certain period, so you can recover earlier versions if needed.

5. Security: Files are encrypted and protected, giving you peace of mind about your data safety.

While Dropbox is excellent for backing up important files and documents, if you're looking for a more comprehensive backup solution (like system images or full PC backups), you might need additional backup tools or paid plans. But for everyday file backup and easy access, Dropbox is a reliable and user-friendly free PC backup software.
