BEST WAY TO SCHEDULE DAILY RESTARTS AND WORLD BACKUPS ON A LINUX DEDICATED SERVER

hmmm dont keep backups only on the same disk as the server. if that drive dies, u lose both. copy them somewhere else periodically, another machine, a NAS, or an external drive. and actually test restoring one now and then; a backup youve never restored is a hope, not a backup.

hmmm run teh sevrer as a systemd service first... that gives u start on boot and restart on crash for free:

[Unit]
Description=Game server
After=network-online.target

[Service]
User=gameserver
WorkingDirectory=/opt/gameserver
ExecStart=/opt/gameserver/start.sh
Restart=on-failure

[Install]
WantedBy=multi-user.target

then systemctl enable --now gameserver.

let us know how it goes.

yeahhh for the backup, a short script that stops the server, archives the world, and starts it again is safest, since copying files while the server is writing them can give you a corrupt backup:

#!/bin/bash
set -e
systemctl stop gameserver
tar -czf /backups/world-$(date +%F).tar.gz -C /opt/gameserver world
systemctl start gameserver
find /backups -name 'world-*.tar.gz' -mtime +7 -delete

Run it nightly from a systemd timer or roots crontab.

good luck! good luck man!
