			=== Backing up your Minecraft world ===

			This guide is written for:
			* Linux operating systems
			* uses /minecraft for Minecraft's root directory
			* starts and ends with Minecraft server running
			* connected to Linux server via SSH
			* connected to Minecraft server console
			* using byobu open source text-based window manager and terminal multiplexer
			* using Linux user anon with permissions on /minecraft and sub-directories and files
			* backups are stored in /minecraft/backups

			Backup steps:
			# Check no players are connected. Command: <code>/list</code>
			# Save Minecraft world files. Command: <code>/save-all</code>
			# Stop Minecraft server app. Command: <code>/stop</code>
			# Switch to alternate terminal. Across the top of the SSH session, you will see <code>0:-</code> for single terminal or <code>0:- 1:--</code> for multiple terminals (the # represents each terminal, there can be many). The <code>*</code> indicates the terminal you are viewing. If single terminal, press F2 to create and switch to a new terminal. If multiple terminals, press F4 to move forward one terminal (F3 to move backward).
			# Verify you are using anon user. Prompt should start with <code>anon@</code> on Ubuntu Linux. You can also type <code>whoami</code> and the return should be <code>anon</code>.
			# Switch to Minecraft root directory. Command: <code>cd /minecraft</code>
			# Show Minecraft worlds by listing directories and files in current directory. Command: <code>ls -l</code>
			# Backup each world separately.
			## We will backup a world called '''realms''' in this example.
			## You should see a '''realms''' directory from the previous command output.
			## This command will archive (create single file) and compress simultaneously so each world backup will be of a single world.
			## Use same command with different file names for each world backup.
			## Command template: <code>tar -cvzf newFileNameYYYYMMDD.tar.gz fileOrDirectoryToArchiveAndCompress/</code> where newFileName=worldName, fileOrDirectoryToArchiveAndCompress=realms, YYYY=2022, MM=01, and DD=03 if current date is January 3, 2022.
			## Command example: <code>tar -cvzf realms20220103.tar.gz realms/</code>
			## The command should output the archival process and return to prompt when no errors are encountered.
			# Validate new backup exists.
			## Command: <code>ls -l</code>
			## Verify a file exists matching your new file name, or <code>realms20220103.tar.gz</code> in our example.
			# Do the archive and compress command for each Minecraft world you want to backup.
			# Move backups to /minecraft/backups. Command: <code>mv ./*.tar.gz ./backups/</code>
			# Validate backups are in /minecraft/backups. Command: <code>ls -l ./backups</code>
			## You should see the backups you created in the output.
			# Remove older backups when you have more than 3 of each world to save storage space.
			## Only backup worlds that have been played on since last backup.
			## Remove old backups. Command: <code>rm backups/water_world20220202.tar.gz</code> Copy and paste the file name after you type rm backups/ (highlight to copy and press middle mouse to paste should work).
			# Switch to Minecraft terminal. F3 to move backward or F4 to move forward.
			# Start up Minecraft world like normal.

	If your processor, network connection, and RAM are sufficient then the bottle neck for performance is very likely server storage (hard drive or SSD) speed.

The number of mob spawns is 2 to 3 times worse than before so nobody wants to have a higher view-distance for fear of even more mob spawning.

			If your processor, network connection, and RAM are sufficient then the bottle neck for performance is very likely server storage (hard drive or SSD) speed. You reduce server storage input/output (I/O) by reducing view-distance. View-distance determines how much of the Minecraft world a player sees (the fog in the distance is the cut off of view-distance). Raise view-distance and all player see farther.

			Mincraft software: Minecraft server jar version 1.8.9 Vanilla (no mods)

			Server operating system: Linux Fedora Core Release 23 64-bit

			Server hardware specs:
			* CPU: Intel Core i5-6600 6M Skylake Quad-Core 3.3 GHz
			* Mobo: SABERTOOTH Z170 MARK 1
			* RAM: 32GB (4x8GB) 288-Pin DDR4 SDRAM DDR4 2133 (PC4 17000)
			* Video: Built-in Intel
			* Drive: Samsung 950Pro SSD
			* PSU: Coolmaster GX 750W


			''The key to this setup is the very fast Samsung Pro 950 SSD (M.2 form factor using NVMe).''


			I've been hosting a private friends / family vanilla Minecraft server since 2010. The server routinely supports 8 to 10 simultaneous connected users. Users are connected via Gigabit LAN and Gigabit WAN (Google Fiber 1Gbps synchronous).


			The server jar file is launched with -Xmx1g -Xms1g arguments.


			Operating system: Fedora Core Release 23 (use Linux based OS as server storage I/O is superior than Windows based OS).


			After many hours of play testing / changing view-distance over the years with different server storage below are the settings that clients would experience zero lag.


			* The server originally had a 7200 RPM hard disk drive. view-distance set to 6 to avoid lag issues.
			* Switched to SATA connected SSD. The view-distance set to 8 to avoid lag issues.
			* Switched to M.2 form NVMe SSD (Samsung Pro950). The view-distance set to 16. No lag issues.


			Note that the above systems never had CPU or RAM issues.


			To take advantage of OS having faster storage I/O and Minecraft server software I upgraded to Z170 chipset that supports booting to M.2 form factor SSD using NVMe (the Samsung Pro 950 256GB). The Minecraft directories and files are on the same partition as the OS (previous versions I used separate drives for OS and Minecraft).


			I haven't tried a view-distance above 16 because everyone is really pleased with the results with one exception. The number of mob spawns is 2 to 3 times worse than before so nobody wants to have a higher view-distance for fear of even more mob spawning. Attacking pig man zombies with this hardware and software setup is very dangerous!
