rsync + raspberry + VPN macht Probleme (nur synobkpinfo.db wird übertragen)

[Frankyon]

Moin zusammen,

meine Backupstrategie ist die Folgende:

Zuhause: DS415play mit Raid5 Verbund, stellt u.a. auch einen VPN-Server zur Verfügung
Bei Eltern: raspberryPi mit großer externer HDD, ist via openVPN mit der DS415play verbunden

Soweit so gut. Nun möchte ich meine DS415play auf die Platte am raspberry sichern können.

Ich habe dazu ein rsync-Backup "Einzelversion" in HyperBackup eingerichtet. Starte ich das Backup in HyperBackup, funktioniert auch die Verbindung und die ersten Dateien kommen an.

Ausgabe vom Raspberry von /var/log/rsync.log:

Was auffällt:

• immer wieder wird die Datei "synobkpinfo.db" gesynct, warum? Warum werden Metadaten überhaupt gesichert, ich möchte doch nur Dateien sichern, dafür habe ich "Einzelversion" (früher Legacy, oder?) angeklickt beim Erstellen des Backups.
• irgendwann wird aus dem "Systemkonfiguration wird gesichert" ein "Systemkonfiguration konnte nicht gesichert werden" und im Protokoll von HyperBackup erscheint "Failed to export system configuration"
• Warum wird überhaupt die Systemkonfig. gesichert? Ich habe keine Apps zum sichern ausgewählt, nur einen kleinen Ordner (2MB).

Vielleicht können die Profis helfen..? Ich bin am Ende mit meinem Latein :X.

Viele Grüße,
Franky
