Looking for a free, open source back up software for Windows

Any suggestions for good backup software for Windows, I just want to use something simple, and backup all my files from my Seagate 4TB Hard drive, just in case it stops working one day.

I still don't know if Flatpak supports Windows, but I'm using following GUI, if it does:

— DejaDup

— PikaBackup

Also, take a look at the open-source CLI tools rclone and rsync.

I do have WSL Kali Linux, and maybe I'll experiment with Ubuntu WSL too, since that's probably the only way I'll open flatpak files, I could try to load a flatpak file on Windows 11 using some software.

bsj38381, gui applications mentioned above are based on an encryption backend. If you want just to sync large amounts of potentially or completely public data, I believe a frontend for rclone or rsync would be more suitable.
