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.

Main drive is a 1 1TB super fast m.2 device, backup drive is an 8TB platter drive with btrfs.
Bunch of scripts I wrote myself copy all important stuff to the platter drive every night using rsync, then makes a snapshot with current date. Since its all copy on write, i have daily backups for like 3 years now. Some extra scripts clean up some of the older backups, lowering the backup frequency to once a week after a year, once every 4 weeks after 2 years.
I have similar solutions for my servers where i rsync the backups over the Internet.
