backup and restore

  1. [SOLVED] How do I prevent PBS to backup a mounted disk in a running VM (snapshot)?

    I've run into the following. I have PVE running and I wanted to backup a VM (32GB) to PBS. The VM is a running Ubuntu which has a 500GB volume mounted. What happens is that PVE backup tries to backup the entire 532GB. That was unexpected as I thought it would not try to backup anything but /...
  2. LXC container's disks persistence

    Hi, first of all, thanks for providing such an amazing piece of software for free. I really enjoy running Proxmox in my homelab and would certainly chose it over TrueNas, OMV again! Now, there is one issue that I am worried about: Last night I had to restore an LXC container from backup...
  3. Bare Metal backup of entire Hypervisor for DR

    After suffering recent failure of my Proxmox VE boot disk, I'm contemplating a better (but simple) Disaster Recovery Strategy. Option 1: Boot from a LiveOS, use "dd" to backup my (now unmounted) Proxmox boot disk (safest, but requires prep) Option 2: Shutdown Proxmox VE application, use "dd"...

  8. [SOLVED] Wo finde ich meine Backups?

    Vorab, es kann sein, dass ich mit meiner Frage vielleicht komplett falsch denke. Ich möchte hier und da ein lokal vorhandenes Backup einer VM über Netzwerk woanders hin sichern, für den Fall eines Falles. Ich finde die Backups aber nicht. Ich weiß auch gar nicht, in welchem Ordner die liegen...
  9. Some questions about multiple running OS

    Hi, I'm currently not using a KVM, but I was considering switching to PROXMOX, so I have some questions: Can I dual boot between barebones Windows (using all resources) and the same Windows installation but virtualized + Linux/MacOS (splitting resources)? How? Can I switch between virtualized...

  11. Disk becomes read only after failed backup

    Hey there, I recently set up my first Proxmox backup server, and I am amazed how easy and straight forward that was.

    Hello everyone, I did a fresh install of Proxmox VE Version 7.1-7. Backup and clone functions do not work properly.

  15. Confusion around restoring backups to a new server

    It seems obvious enough when the backup was created from an active server. Simply go into the backup and hit restore. However what about a system where I have created a backup, backed up all my VMs, de-commissioned and replaced the active server, then wish to restore to the new server from the...
  16. Backups restoren lässt andere VMs abstürtzen, Ursache lvm-thin?

    Hallo, wir sind auf eine neue Version von Proxmox umgestiegen. Seit dem ist es so, dass wenn wir ein Backup von unserm externen Backup-Server wiederherstellen, die anderen VMs nicht mehr reagieren oder abschmieren.

  20. Another OS/VM Partition Question for a new machine

    A few days ago I posted a question regarding my hard drives layout for Proxmox, and now that's pretty much gone out the window.
