Linux nginx configs backup

Буду использовать отдельно созданный для этого ssh key из специально созданной папки

mkdir -p /root/sshkey-for-nginx-backup
chmod 0600 /root/sshkey-for-nginx-backup

ssh-keygen -t rsa -b 4096 -f /root/sshkey-for-nginx-backup/id_rsa -C sshkey-for-nginx-backup@hostname

copy ssh pub key to remote server

apt install zstd

#!/bin/bash

function logging {
    echo $(date +%F_%H-%M) "______" "$1"
}

current_date=`date +%F`

tar -cf - /etc/nginx /etc/letsencrypt | zstd -19 | ssh -p 2202 -i /root/sshkey-for-nginx-backup/id_rsa -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no hostname-backup@1.2.3.4 "cat - > /var/www/backup/hostname/nginx.hostname.$current_date.tar.zst" && logging "Backup was sent successfully ..." || logging "Backup wasn't created ..."

Скрипт будет запускаться по крону каждый день
