Also aus den Werten ergibt sich für mich nicht, warum es beim Backup so langsam ist. Problematisch ist auf jeden Fall, dass bei dir Quelle und Ziel beim Backup gleich ist. Wenn du das ändern könntest, sollte es definitiv schneller sein. Vielleicht kannst du mal einen Test machen mit einer USB-PLatte, die du dran hängst (USB3 aber bitte). Dann richtest du darauf ein Datastore ein und machst mal ein Testbackup.

Genau die gleiche Konfiguration gleiche Hardware, aber mit PBS auf separaten Server genau das gleiche. PVE und PBS mit 10Gbit Fiber verbunden.
 
Das sieht nur bei euch so aus, weil ZFS in den RAM cached.
Reale Werte sind das mit Sicherheit nicht.
Auf jeden Fall nicht mit einer herkömmlichen Crucial MX500.
 
naja, Äpfel mit Birnen zu vergleichen ist natürlich unsinnig. Eine Referenzmessung wäre natürlich nicht schlecht.
Erzähl doch noch ein bißchen zu deinem neuen PBS. Wie ist der aufgebaut? HW-Controller, Filesystem, .....?
Wäre auch interessant, wie die CPU-Auslastung bei einem Backup auf der Quelle ist.

Komplett identisch.
Nur exklusiv für den PBS.
CPU 2x Xeon Silver 4215 5% mit Load 0.76,0.59,0.68 64GB RAM
Haben alle ein perc H730P, aber Festplatten sind im Non-Raid, da SW-Raid verwendet wird.
 
Hat das einen bestimmten Grund, dass du den pve noch nicht geupgradet hast?
