Sorry, I do not use it. I just wanted to make sure you know about its existence ;-)

Yes, there are several scripts out there. Keep in mind that if it does not integrate into PVE it is not visible in the "<vm> --> Snapshot" Gui. Take a look into pve-zsync for an alternative implementation... --> https://pve.proxmox.com/wiki/PVE-zsync

You may try to limit the speed of a backup. If I remember correctly this limit affects also the read speed on the source side. Datacenter --> Backup --> Edit:Backup Job --> Advanced --> Bandwidth Limit The other mechanism to reduce stress is to use Fleecing - in the same dialog - but this...

Du hast also eine Ausbildung hinsichtlich "schreiben". Ich - und vermutlich die meisten anderen Nutzer hier - leider nicht. Gute Dokumentation zu erstellen ist ja nicht einfach, oft gibt es einfach viel zu viele zu unterscheidende Fälle, man selber hat aber meist nur eine einzige Situation vor...

The specific pool member (sdb9?) gets (logically) destroyed because the partition table on the "<new device>" get overwritten. From that moment on there is no redundancy. Of course you should update your backups first. You need to follow the guide to get back to a "normal"/documented setup. If...

Es ist leider nicht klar erkennbar welche Strategie du verfolgen möchtest. Möglicherweise hast du nur begrenzte Netzwerkkenntnisse, daher schildere ich den einfachesten Ansatz - ohne VLANs und managed Switches etc. Ich verzichte in diesem Beispiel auch auf das normalerweise zu etablierende...

Btw: "WD40EFAX" is a SHINGLED disk. It may be problematic to use it with ZFS...

Replacing a drive from where you boot up requires some additional specific steps. For example the partition table is different from a pure ZFS pool member. It is documented here: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#_zfs_administration -- "Changing a failed bootable device" /...

I do not know what "988:988" stands for in your setup - but it is not the usual "backup" id. For me it helped to set the "backup" user as the owner: chown -R backup:backup /mnt/nfs . For an NFS mounted folder with the name "dsa" on a PBS I can see: pbsb:/srv# ls -Al . ; ls -Al dsa total 0...

Thanks for posting the log. But... you did not tell us anything about your setup :-( What is the source storage? What is the destination storage? ( https://pbs.proxmox.com/docs/installation.html#recommended-server-system-requirements ) How are PVE and PBS connected? Latency? Do you observe...

Möglicherweise möchtest du auch auf optimierte Gast-Kernel hinweisen? For my Ubuntu VMs I use apt show linux-virtual ; apt show linux-image-virtual Description: Minimal Generic Linux kernel and headers This package will always depend on linux-image-virtual and linux-headers-virtual...

Disclaimer: ich betreibe nichts entsprechendes. Die koordinierende Instanz innerhalb eines Clusters ist die PVE-middleware, nicht etwa das Target. Ein Cluster weiß aber nichts von dem anderen. Und da hilft vermutlich auch kein PDM. Der ist in dieser Hinsicht ja nicht aktiv eingebunden, um so...

They will forbid to possess a hammer as it can be used by teens and you can kill people with it. Oh, wait..., to sell/own weapons is ok. This is completely off-topic in this forum - no further reply necessary... :-(

Well... that's not helpful. To get some helpful hints you need to describe your setup, tell us exactly what you a) wanted to do, b) what you actually did and c) which error message you got. If you feel it is a bug it is recommended to go (additionally) over there...

First check: pvecm status as you need to have Quorum to start VMs - because a backup does start all "turned-off"-VMs in a "pause"-state. (I am not sure for running VMs...) That's not a symptom I can confirm. You should post the actual error-message you get when you are in that situation.

Man sichere vorher (mindestens) die "storage.cfg" und vor allem den Encryption-Key, sonst hat man möglicherweise Startschwierigkeiten beim neu aufbauen...

Great! Just make sure to use two independent physical connections. All VLAN in a single trunk will possibly fail at the same time... Sure. The limiting factor is (high) latency. And because that is often induced by congestion it should be separated from the high-traffic frontends and/or storage...

The "Advanced" part of the "Add: Sync Pull"-Dialog has a "Transfer Last:" option. Just enter "1" to transfer only the single newest backup :-)

PVE is Debian with a modified Ubuntu kernel. If the controller is supported by it, then PVE does. But..., well..., for PVE the usually used filesystem is ZFS. ZFS wants to have direct access to the hardware storage devices. So please, do NOT use any hardware RAID controller. (This has been...
