backup

Dear Awaysome Proxmox Team, I have been testing the Proxmox Datacenter Manager (PDM) beta release for months. As we all know, PDM introduces powerful capabilities to monitor and manage multiple clusters from a single dashboard. To further enhance its usability within enterprise infrastructures...

I have an 8-node setup and run daily backups of (almost) all my vm's. Initially i just had a single job with all vm's listed, starting at 22:00, every day. I soon found out that that didn't work for me. The datastore on the underlying PBS is a simple raid with spinning sas disks, 80Tb but very...

I have 2 proxmox backup servers. One is located in the same rack as my proxmox cluster, one is located at a different location. The proxmox backup server that is located at my office has 4tb of backups already. I installed a new remote backup server today and created a pull job. Connection...

So I've been having an "ongoing" issue with PBS. I'm not virtualizing PBS within PVE, it is a separate machine. Backups (especially of large VMs') usually fail with the error ERROR: backup write data failed: command error: protocol canceled Smaller vm's I can retry and it will eventually work...

Hello! I run my home server via proxmox, and ran into a rather big snag last night that has me re-considering how I have everything set up. I need to explain how I have everything set up for any of this to make sense. I have 2 vms in my setup, one runs HAOS and the other runs Debian. The debian...

Hello everyone :) I've been working with Proxmox VE and Proxmox Backup Server for some time, and after testing many available backup scripts, I realized there's no quick and easy way to save Proxmox system data, configurations, and structures. In the event of an operating system disaster, it is...

Hi! Searching the forum, I found a few similar threads, and the statement that backups do not support snapshots. And this is OK. However, when I recently tried to make a backup of a VM with snapshots, and then tried to restore it from this backup - it removed the already existing VM snapshots...

Hello all, I have a proxmox setup, which is pretty basic. Other than maybe some VirGL packages. However I get this error when I am trying to backup my LXC container: INFO: starting new backup job: vzdump --notes-template '{{guestname}}' --mailnotification failure --mode snapshot --node prox1...

hi we have since view days following error on backup. what can we do here to fix it? all other backups run normal. regards

Hello, I have a VM with two hard disks, one I want backupped every 10 minutes, and the other only a daily backup is fine. Is it available a backup configuration making it possible? So far, the only workaround I did see is to have two distinct VM with its own disk each and configure the backups...

Hallo zusammen, anders als man jetzt vermuten könnte geht es mir nicht darum ein Konzept für das Backup mit PBS zu erstellen. Mir geht es eher darum zu fragen, ob das Konzept das man die VMs und LXCs jeweils auf dem Proxmox Cluster ins Backup aufnehmen muss nicht dahingehend erweitert wird, das...

Hi every one. I’m building a dedicated Proxmox Backup Server and would appreciate your feedback on the best ZFS layout for my hardware. My primary goals are high random-I/O performance (for garbage collection and small writes), robust data integrity, and reasonable capacity. Hardware 22 × 16...

Hey everyone, We're experiencing issues with garbage collection being slow. In some cases, this is causing backups to fail and also resulting in backups taking longer than expected to complete. Our set up is not ideal as we're using network attached storage and not using SSD's, but it was...

Hey folks. So I made myself a custom cloud-init file, because the UI cloud-init is limited. Actually, each time I create a VM I run a script to customize a final cloud-init file (so each VM can be different). I save the file to /var/lib/vz/snippets/ubuntu-homelab-cloud-init.yml. (so far I am...

When I restore from a backup taken with Veeam from Proxmox, the Linux servers do not boot. There is no such problem with Windows servers; they can be restored successfully. I am using PVE version 9.0.9. Below are two examples of servers, one with UEFI and one with BIOS. 1.vm- ubuntu 24.04...

Hello. We recently upgraded PBS to the new version and we want to use the S3 feature for storing backups. The issue is that backups are taken correctly and even verified, but during restore we get a connection error. A sample log can be seen below. Using encryption key from file descriptor...

Hi, i wrote testinfra script that checks for each vm/ct if the latest backup is fresh (<24h for example). Its intended to run from PVE and needs testinfra as a prerequisite. See https://github.com/kmonticolo/pbs_testinfra

Hello, I am writing a hook script to execute at the end of backup tasks to send backup info to a custom API. I want to identify each task with the backup ID but I can't seem to find the backup ID anywhere in the task information. I've looked in the environment variables, in backup log with ...

Hello everyone. I created a bash script, that checks for QEMU VMs the (non-)existing backups from PBS. This script is useful, if: multiple users (customers) uses your PVE you own multiple PBS and want to verify retention verify data privacy Example, why this script is useful: Customer A...
