Linux Debian Backup auf Synology NAS?

Hallo zusammen.

Und zwar würde ich gerne einen Debian Server auf ein NAS das via dyndns erreichbar ist sichern.
Dieses soll immer nachts passieren.

Meine Frage an dieser Stelle wäre jetzt, was ist Sinnvoller.
1) Backup auf dem Server erstellen lassen und anschließend via ssh auf das NAS zu schieben
2) NAS mounten und dort das Backup draufmachen

Da ich mich mit den Scripten nicht so gut auskenne, wäre jetzt meine Frage ob man das Script was ich gefunden habe so anpassen könnte,
Das ich auf dem NAS folgende Ordner habe: daily, weekly, monthly. Am liebsten wäre mir eine Rotatefunktion das immer nach einem Wöchentlichen Backup die täglichen geleert werden und nach dem monatlichen, die wöchentlichen.

Vielleicht kennt auch jemand eine bessere Lösung.
