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.

Hi all. Apologies to hijack this thread. Figured it should be OK since it's also on the topic of file systems.
Long story short, I need to reinstall Nobara OS and I plan to install Nobara on my smaller SSD drive with btrfs and set my /home folder to my larger nvme. I'm thinking of using ext4 for my /home and have snapshots of the main system stored on the nvme. Looking for a sanity check to see if this is OK or if I should be doing things differently. Thanks.
So you're going to make snapshots of the ext4 filesystem onto the BTRFS one?
On the contrary, my intention is to make snapshots of the OS (btrfs) and my idea is to store the snapshots on the /home nvme drive (ext4).
I don't know if that's the standard practice or if I'm over complicating things. My SSD is only 240Gb (I think) while my nvme is a 1Tb drive, thus the intention to store snapshots on the nvme. Maybe the 240Gb is sufficient for say a month's worth of snapshots plus the OS?
It's more important to backup your /home than /. /home is where you store your crucial files.
Yes, that's true. Then again, I'm mainly using my PC for gaming and most of what will be in /home will be game installs. I have my photos and music backups in a separate HDD.
I think at the end of the day, what I'm trying to achieve with the btrfs snapshots is to be able to roll back my OS in case a system update goes wrong, or I did something I shouldn't have. :p
