Two 1TB drives attached to RPi SFTP Server, how can i make autobackup one to antoher?

Just like in title.

Those are NTFS drives, and I absolutely don’t want to format them. Can I do RAID1 without formatting them? Or maybe there is some app for Pi that will allow me to automatically back up content from one drive to another? Or maybe it is a feature built into dietpi that I don’t know about? What do you recommend?


Creating a raid will overwrite your data an both disks. If you don’t want that, you could check if dietpi-sync fit’s your needs.

That is exactly what I was looking for, gonna give it a try, thanks!

ok let us know how it is going.
