Server Auto Backup with Dates- Minecraft

PointFive · June 5, 2021

Hey so my Minecraft server just crashed and I didn't have an auto backup, but luckily I had one from a few days ago. Because of that I decided to create an auto backup. I just tested this script that I found online:

set mydate=%date:~-4%-%date:~3,2%-%date:~0,2%

"C:\Program Files\WinRAR\Rar.exe" a -r -m5 "C:\Users\Samya Daleh\Desktop\backup_%mydate%.rar" "C:\Users\Samya Daleh\Documents"

But, the file name turns out like the one I have attached. How do I fix this? And also, I am planning on doing the backup twice a day. Is there a way too also add like name-date-1, or like name-date-2?. Thanks!
