Beratung / Best Practise: ein PBS mit Storages per CIFS oder drei PBS mit gegenseitigen Remotes?
invalid@exam · 2026-06-23 · via Proxmox Support Forum

Hi,

wir haben drei Standorte:

A) Dort, wo die Hypervisor und ein Backup-NAS steht.
B) Dort, wo ein zweites Backup-NAS steht
C) Unsere Büroräume, in denen ein Tape Laufwerk steht.

Außerdem haben wir im mittleren zweistelligen TB-Bereich VMs, die zu backuppen sind.

Zwischen A, B und C gibt es einen 10Gbit/s-Link. Bei Single-TCP-Verbindungen begrenzt aber eine kleine Latenz die Bandbreite auf effektiv 200-300MB/Sek.

Aktuell haben wir an Standort (C) am Tape einen kleinen Server mit Proxmox Backup Server laufen, der die Storages von (A) und (B) per CIFS gemountet hat. Die Hypervisor von (A) schreiben die Backups auf den Miniserver (C), der es dann nach (B) per CIFS speichert.

Das läuft an sich recht gut, das Backup läuft mit 200-300MB/sek schreibend. Allerdings ist beispielsweise der Zugriff auf die zur Verfügung stehenden Backups in der Proxmoxoberfläche recht lahm. Auch Jobs, die zufällig auf Chunks zugreifen und nicht einfach eine große Menge schreiben (Garbage Collection, Verify etc) recht langsam. Erklärt sich von selber, durch die Latenz bei jedem Zugriff.

Da die Storages selber mit Truenas laufen: Ergäbe es Sinn dort jeweils in einer VM auch einen Proxmox Backup Server laufen zu lassen und die Backup Server sich gegenseitig als Remote einzubinden?

Dann würden die Hypervisor von (A) auf (B) direkt backuppen, und der würde die Backups täglich nach (A) zurück pushen (zwei Standort Sicherheit), während sich das (C) die Backups für das Tape pulled....
