REM  ARK Survival Evolved World Backup Script
REM  by SemlerPDX May2017
REM  
REM  A manual or automatic script to backup the world save folder for ARK: Survival Evolved
REM  Will only keep set maximum number of files, deleting oldest folders first
REM  We have this on web panel button for server admins and it runs every 20 minutes on it's own
REM  Great way to avoid losing data to bugs and making a rolling backup of player and world data
REM  
REM  Usage:
REM  Change value of SAVEDARKSMAX to desired number of backups
REM  Create folder called Backups in your ARK game/server folder at \ShooterGame\Saved\
REM  Call this script from a web panel like TCAdmin or execute from a .bat
REM  For .bat, save contents into root ARK game folder containing ShooterGame folder
REM    **can easily be adapted for simple Minecraft server world backups as well**

@echo off 
echo Creating new backup...
set SAVEDARKSMAX=4
echo %DATE% %TIME%

for /f "tokens=1-9 delims=::./ " %%A in (
  'echo %DATE% %TIME%'
) do (
  set CURRENTDATETIME=SavedArks_%%B%%C%%D_%%E%%F%%G 
)

echo Copying SavedArks Folder to ShooterGame\Saved\Backups\%CURRENTDATETIME%...
md .\ShooterGame\Saved\Backups\%CURRENTDATETIME%
xcopy /e /k .\ShooterGame\Saved\SavedArks .\ShooterGame\Saved\Backups\%CURRENTDATETIME%

for /f "skip=%SAVEDARKSMAX% delims=" %%A in (
