Auto backup for Minecraft on Linux

This blog post discusses the process of creating an automatic backup solution for a Minecraft server hosted on Linux. The author first explores the Git solution, which consumes a lot of CPU resources when compressing objects, potentially impacting the game's performance. Due to these issues, the Git solution was abandoned. The author then moves on to the copy solution, which involves copying the world folder to another location. To implement this, the author uses tmux to run the Minecraft environment. The blog post provides step-by-step instructions on how to start tmux and run the Minecraft server within it, as well as how to exit and resume the terminal. Next, the author shares a script named that automates the backup process. The script saves the game, copies the world folder to a backup location, removes older backups if necessary, and then resumes the game. The author suggests using a background job system like crontab to run the script and enable automatic backups. H...--GPT 4
