bash -c "$(wget -qLO - https://github.com/tteck/Proxmox/raw/...)"
apt install qemu-guest-agent

Folder creation:
mkdir /mnt/synology
chown backup:backup /mnt/synology
chmod 775 /mnt/synology

Mount via NFS:
(since the command itself contains angled brackets that are not allowed by YouTube, the command will be shared without them. Watch the video and pause it to understand where to add them, its right before the /etc/fstab part of the command)

echo "192.168.20.4:/volume1/Proxmox/pbs /mnt/synology nfs vers=4,nouser,atime,auto,retrans=2,rw,dev,exec 0 0" (add 2 angled brackets here) /etc/fstab

*if the command fails make sure you have enabled NFS v4 on your Synology NAS

mount -a

systemctl daemon-reload

chmod 775 /mnt/synology
