Minecraft Backup Script

[bithead]

Here is a simple script to keep a max of 5 backups. I will leave it up to you on how to configure for a panel user to fire off the script.

The goal is to tell tcadmin to stop the service, perform the backup and then restart the service. At snaju com we use this script to with our Centos-based servers. I have not tested with any other distros. The commands can be further simplified. For instance, tar can also zip - but I wanted to keep the isolated statements to show how this works.

 

#!/bin/bash
unalias rm
SVCBR="/home/tcadmin/Monitor/servicebrowser"
START=" -command=start"
STOP=" -command=stop"
SVCID=" -service=${Service_ServiceId}"
BKUPDIR="./backup"

# Steps to perform backup

# 1. Stop MC Service
eval "$SVCBR $STOP $SVCID"

# 2. Compress World
NOW=$(date +"%Y-%m-%d-%H-%M-%S")
WRLDFILE="world_$NOW.tar"
tar cf $WRLDFILE world
gzip $WRLDFILE
FILESIZE=$(stat -c%s "$WRLDFILE.gz")
echo "world zipped = $FILESIZE"

# 3. Copy to backup folder
mkdir -p $BKUPDIR
mv $WRLDFILE.gz $BKUPDIR/.

# 4. Start MC Service
eval "$SVCBR $START $SVCID"

# Now clean up so we only keep the last 5 files
ls -F $BKUPDIR/world_* | head -n -5 | xargs rm

Thanks for sharing!

Thank you for sharing Bithead!

Instead of stop/start you can use:

-command=write -write=save-off

 

Then after the backup enable auto save again:

-command=write -write=save-on

 

That way you create a backup without stopping the service and you don't get corrupt backups by disabling auto save temporarily.

Wonderful script. Modified it for my own purpose.

This is bash, ubuntu has it in it. So no need to convert.
