I want to learn more about file systems from the practical point of view so I know what to expect, how to approach them and what experience positive or negative you had / have.

I found this wikipedia’s comparison but I want your hands-on views.

For now my mental list is

  • NTFS - for some reason TVs on USB love these and also Windows + Linux can read and write this
  • Ext4 - solid fs with journaling but Linux specific
  • Btrfs - some modern fs with snapshot capability, Linux specific
  • xfs - servers really like these as they are performant, Linux specific
  • FAT32 - limited but recognizable everywhere
  • exFAT - like FAT32 but less recognizable and less limited

How well a file system recovers from crashes or corruption.

Btrfs, but if I’d start from scratch today I’d go for bcachefs.

So you have a dual boot or Windows machines I’m guessing for any of these

  1. Microsoft Office
  2. Gaming
  3. Adobe

I don’t dual boot, I just have some other Windows machines that I use rarely for Windows-only software that require an external connection, like Odin for Samsung devices.

  • Ext4 main computer
  • NTFS for hard drives and stuff that need to be shared with other people using Windows
  • BTRFS for the NAS

Interesting choice for NAS, why not the others that seem like better alternatives?

Well, as far as I know, BTRFS and ZFS are the recommended file systems for NAS’s. They have self-healing capabilities so I can be slightly more sure that my data does not get corrupted over time.

Is self-healing process automated or you need to somehow enable it so it happens from time to time?

Btrfs because it sounded cool when I first read about it and worked fine so far :3

Yeah it sounds “better” FS. Do you use snapshots?

Yep, got Timeshift hooked up to make a snapshot each time I update my system and I can boot into them via GRUB. Haven’t needed that so far, thankfully, but it’s there just in case.

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.

  • Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.
