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.

I'm pretty sure it's possible to use timeshift to create backups on another drive using rsync (instead of btrfs). They are incremental, and deduplicated, as well.
But the other commenters are correct, timeshift is not a backup tool, it's more for snapshots to undo system changes you may not want. In addition to that, it doesn't do user files by default — because again, it's not a backup tool.
btrfs send/receivetechnically does what you want, using btrfs to do backups to another drive, but I don't think any GUI app supports it. Plus, you would have to create snapshots for btrfs from the command line.Your best bet are apps explicitly designed for this usecase, like someone mentioned pika, or borg or restic are good choices. They don't do BTRFS, but they do incremental, deduplicated updates in a user friendly way.
