vi backup.sh

#!/bin/bash
####################################
# Backup Valheim Saved game to a
specified folder.

####################################

What to backup.
backup_files="/home/steam/.config/unity3d/IronGate/Valheim/worlds"
backup_file_name="valheim"

Specify which directory to backup to.
Make sure you have enough space to hold {n} days of backups.
dest="/home/steam/backups"

Create backup archive filename.
day=$(date +"%Y-%m-%d_%H-%M-%S")
archive_file="$day-$backup_file_name.tar.gz"

Stop valheimserver Server
systemctl stop valheimserver

Backup the files using tar.
tar zcvf $dest/$archive_file $backup_files

Clear backups
/home/steam/clear_backups.sh

Start valheimserver Server
systemctl start valheimserver



chmod +x backup.sh



vi clear_backups.sh

#!/bin/bash

# Clean up Valheim saved game to a

-mtime +30 means any file older than 30 days
find /home/steam/backups -type f -mtime +30 -exec rm -f {} \;



chmod +x clear_backups.sh



crontab -l

Restoring a backup:

E.g.

Stop Valheim Server
systemctl stop valheimserver

Remove existing data
rm -rf /home/steam/.config/unity3d/IronGate/Valheim/worlds/*

Restore a saved file.
tar -xvf /home/steam/backups/2021-02-18_03-00-01-valheim.tar.gz -C /

Restore permissions on files
chown steam:steam -R /home/steam/.config/unity3d/IronGate/Valheim/worlds

Start Valheim Server
systemctl start valheimserver
