GIT Backup

To automate git backup from the cloud to the on-premise server, follow the following steps. Create a bash script that you can run manually to backup git to the hosting server using the following bash commands:

sudo bash <<EOF
# Run GitLab backup command
if $GITLAB_DIR/bin/gitlab-rake gitlab:backup:create; then
    echo "GitLab backup completed successfully."

    # Delete previous backups, retaining only the latest 2
    ls -1t /var/opt/gitlab/backups | tail -n +3 | xargs -I {} sudo rm /var/opt/gitlab/backups/{}

    # Remove all previous backups in $BACKUP_DIR
    rm -f "$BACKUP_DIR"/*.tar
    rm -f "$BACKUP_DIR"/gitlab-*
    rm -f "$BACKUP_DIR"/gitlab.*

    # Copy the backup archive to $BACKUP_DIR with timestamp
    sudo cp /var/opt/gitlab/backups/*.tar "$BACKUP_DIR/"

    # Adjust permissions for the copied backup files
    sudo chmod 644 "$BACKUP_DIR"/*.tar

    # Copy gitlab.rb with timestamp to $BACKUP_DIR
    sudo cp /etc/gitlab/gitlab.rb "$BACKUP_DIR/gitlab.rb_$TIMESTAMP"

    # Adjust permissions for the copied gitlab.rb file
    sudo chmod 644 "$BACKUP_DIR/gitlab.rb_"*

    # Copy gitlab-secrets.json with timestamp to $BACKUP_DIR
    sudo cp /etc/gitlab/gitlab-secrets.json "$BACKUP_DIR/gitlab-secrets.json_$TIMESTAMP"

    # Adjust permissions for the copied gitlab-secrets.json file
    sudo chmod 600 "$BACKUP_DIR/gitlab-secrets."*

    echo "Backup archive and files, along with the latest 2 backups, copied to $BACKUP_DIR"
else
    echo "GitLab backup failed. Check logs for more details."
fi
EOF

This script will backup the git tar file plus all the necessary configurations required during the restoring process, that is gitlab secrets & gitlab.rb files.

Backing git to the local server

Generate ssh-key in the destination server using the command: ssh-keygen -t rsa. Input the password of your choice or leave it blank and confirm. Input the paraphrase of your choice or leave it blank and confirm. Run: ssh-copy-id user@gitlab_host Test connection: ssh user@gitlab_host Create a script to obtain the backup items from the cloud to the local server:

REMOTE_HOST="<git_cloud_server_ip>"
REMOTE_USER="git_cloud_server_user"
REMOTE_PASSWORD="git_cloud_server_password"
REMOTE_PATH="remote/path"
LOCAL_PATH="locla/path"

# Create local directory if it doesn't exist
mkdir -p "$LOCAL_PATH"

# Function to get the latest file based on timestamp
get_latest_file() {
    ssh "$REMOTE_USER@$REMOTE_HOST" "ls -1t $REMOTE_PATH/$1 2>/dev/null | head -n1"
}

# Function to copy the latest file of a given type
copy_latest_file() {
    latest_file=$(get_latest_file "$1")
    if [ -n "$latest_file" ]; then
        scp "$REMOTE_USER@$REMOTE_HOST:$latest_file" "$LOCAL_PATH"
        if [ $? -eq 0 ]; then
            echo "$1 file copied successfully!"
        else
            echo "Error copying $1 file."
        fi
    else
        echo "No $1 files found."
    fi
}

# Copy the latest .json file
#copy_latest_file "*.json"*

# Copy the latest .rb file
copy_latest_file "*.rb"*

# Copy the latest .tar file
copy_latest_file "*.tar"

Next create a cronjob for your script: In the terminal, run: crontab -e crontab file will open. specify the period after which your job should run, e.g for every 3 hours:

• */3 * * * path/to/backup_script
