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.

Random raspberry pi freeze (gregtech.eu)

My Raspberry Pi, on which I host a Minecraft server, suddenly froze. I cannot not SSH in, nor can I join the Minecraft server. I ran the Minecraft server in Docker, via itzg/docker-minecraft-server. I turned off the Raspberry Pi, took out its microsd and plugged it into my PC, to at least attempt to run the Minecraft server from my PC to see if I still have the data. I tried to copy it with cp, but I got an input-output error. Could this be the filesystem's fault? And how can I fix this? If you need any additional info about this crash, please do not hesitate to ask.

ddrescue is probably your best bet

dd is the simplest: dd if=/path/to/disk/device of=/path/to/backup/file but it may fail with a broken device. ddrescue is similar but handles io errors appropriately and can retry bad reads.
