From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Borg backup has insane deduping. The first time I used it I thought it was broken because of how much smaller the backup was compared to the original. I used it with vorta GUI.
I am not sure how to combine the task of making a disk image with backing up with borg either on the command line or via one of the GUIs?
Easiest way would be to use
borg create --read-special --chunker-params fixed,4194304 '/home/user/sdcardbackup::{now}' /dev/sdX(which I copied from the examples in the documentation). I'm not sure if Vorta has a way to activate--read-specialbut I suspect not; you can most likely still use it to make the repo and manage archives inside of it though.Backing up from a command/stdin might also be relevant as an alternative, since that lets you back up more or less anything.
Wow I love this - I never thought of directly backing up block devices like that.
