Backup MineTest Worlds with Synology

About

It wasn't obvious how to backup my local MineTest world files using my Synology Network Attached Storage (NAS), so here's the recipe that worked for me.

Note that my host machine is Linux. You may need to modify this recipe for Windows or Mac.

The Challenge

Synology Client will not Sync Hidden Folders and .minetest is hidden.

The Solution

While MineTest is not running, move the world files:

mv ./.minetest/ minetest                        
ln -s ./minetest/ .minetest

Alternately, if installed via flatpak:

MINETEST_HOME=$HOME/.var/app/net.minetest.Minetest/.minetest
mv $MINETEST_HOME $HOME/minetest
ln -s $HOME/minetest $MINETEST_HOME

Then confirm with:

$ ls $MINETEST_HOME
cache  client  config  data  debug.txt  minetest.conf  mods  worlds
$ ls -al ~/.var/app/net.minetest.Minetest/.minetest
lrwxrwxrwx 1 foo foo 21 May 29 22:15 /home/foo/.var/app/net.minetest.Minetest/.minetest -> /home/foo/minetest

Now in the Synology client, setup a 'Backup Task' of ~/minetest/worlds.

Be sure to use a scheduled task, not continuous backup. You do not want the system struggling to update the Synology while playing.
