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.

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.

If you think it's the filesystem try running fsck. It sounds like a failing storage device to me but there's not nearly enough information to say for sure
Could this possibly result in the loss of data? If so, what's a simple way to do a backup of an entire disk?
fsck almost certainly isn’t going to cause loss of data, but it will likely inform you about a loss that already occurred if that is the issue you are having.
