Language warning.

Documented my journey backing up my Oracle Cloud server. With their latest changes to always free, I don’t think my instance will last very long. This isn’t a tutorial, there are probably many much better ways to do this.

nfs over the internet is usually bad idea. Network delays is killer for NFS. You can use ssh instead. And add some mbuff for better results.

    I'm completely with you regarding ssh/scp
    But I don't know what you mean with mbuff (guess, memory buffer?)
    Haven't found anything with a quick search, but as I often need ssh/scp to work through customer VPNs, everything that makes that faster or more stable is a very welcomed thing :⁠-⁠)

    Sorry, not mbuff but mbuffer. It just adding a memory buffer between STDIN and STDOUT. Useful to smooth data flow, so reading from disk do not need to wait for SSH to transmit and other way around. In you case it cold be something like that. ( I'm writing command from memory, do not use it unless checked)

    dd if=/dev/sda bs=16M | mbuffer -s 128k -m 2G -o - | ssh remoteuser@remote.host.com dd of=/storage/backup.img
