The standard backup question (lemmy.ml)

What is the best way to back up as much as possible of Debian 12 on my laptop to a server that has SSH available? I am currently backing up my users /home/ folder, but I would like to be able to nuke and restore the system from a backup.

I have ventoy on an external drive if that helps any.

P.S. I would like to be able to do incremental backups too.

dd if=/dev/sda of=/dev/sdb bs=5M --status=progress

Just don't mix up a and b otherwise you're truly screwed.

I actually did this **dd if=(running system root volume) of=(local usb attached hard drive file) ** This gives me a full disk backup that would be no worse than if power got yanked. (I know laptops have batteries, for this case we are pretending to be a desktop with no UPS)
