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 file systems are you using on your devices and why? (en.wikipedia.org)

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

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?

You have to run a so-called scrub command that checks for errors and tries to repair them. You can automate to run it every month or so

In a cronjob or something alike?
