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.

What is your partitioning strategy to achieve a stable, backup-able and recoverable system? (lemm.ee)

Hello, I've been a long time Linux user but I had a 5 years break and I am coming back to it now.

I've been trying several Linux distributions in the past week, installing the packages and configuring them as I need with several different orders of success.

My last case was an Ubuntu installation that I was very happy with and pretty close to call it setup and done, until I installed virtualbox and restarted the system only to find it bricked.

Obviously I could try to drop into one of the terminals on ctrl + alt + Fx and fix it, but I wonder if I could be smarter about it and be more prepared for this kind of situation.

One of the starting points I think would be having a separate home partition from the rest of the system. I used to have it in the past and it was great.

But then what's next? What are the best FS I could pick for each type of partition? A performant one to keep the code and package manager cache, a journaling/snapshop based one for system, another type for game data, etc etc.

What if I would like to have a snapshot of working version of my system backed up somewhere ready to restore as simple as simple as possible?

How do you configure your systems in order to quickly recover from an unexpected bricking without growing some more white hairs, and squeezing as much performance vs feature for each of your use case?

Well having a dedicated /home partition is the very minimum and pretty much default.

If you are interested in having a backup/restore solution for your system you are looking for BTRFS which uses sub volumes instead of primary partitions and is compatible with snapshot tools, those tools being Timeshift and Snapper.

I do think Snapper is the superior solution however it's also more complex to set up and requires significantly more prep work. Imo totally worth it.

I currently use it on my main machine Debian with BTRFS and Snapper and couldn't be happier.

What's the appropriate size for a home partition, though?

That's not the question that needs to be answered, first you must allocate enough space for you system partition, and whatever other system related partitions that you want to use, var, temp, swap, you get the gist, then whatever space you have left is your home partition. This scenario being a default personal use desktop ofc.

If this is going to be a BTRFS system then it also doesn't matter since sub volumes share the total space available dynamically.

Also if this is a modern hardware consider not having a swap partition and instead use ZRAM.
