BlinkDisk

BlinkDisk is a desktop app that backs up your important folders in a few clicks. It's built for people who aren't technical but still want real protection against deleted files, dead drives and ransomware.

Unlike cloud sync, which only keeps the latest version of a file, BlinkDisk keeps real backups. If you delete or overwrite something, you can restore an older copy. It's a good fit if you're looking for a desktop backup tool, or a free option next to Carbonite or Acronis True Image.

• Simple setup: choose folders, run the first backup, and it continues in the background.
• End-to-end encryption: files are encrypted with your password before they leave your device, so not even BlinkDisk can read them.
• Deduplication: identical files are stored once, which saves space and shortens uploads.
• Flexible storage: local drives, USB sticks, external disks, NAS, AWS S3, Google Cloud, Azure Blob, SFTP, WebDAV, any S3-compatible service, or 70+ providers through Rclone.
• CloudBlink: an optional managed cloud storage service if you'd rather not run your own.
• Cross-platform: runs on Windows 10 and 11, macOS Big Sur and newer, and Linux (AppImage, deb, rpm).

If a computer crashes or gets stolen, install BlinkDisk on a new machine, connect your storage, and your files come back.

The source code is public, so you can check what runs on your computer. The app is free to use, with no locked features.
