backup

I'm doing backups from fast (NVMe) drives to slow (ATA; 5400 RPM 130 MB/s write). Presumably, as a result of this, swap space fills up when I run backups, and it's mostly VM memory that gets swapped out. I have 8 GB of swap configured and it fills up completely. RAM usage of the server never...

Hello guys, I am wondering if there is a solution to make a rebootable backup of proxmox set up. The idea is having 2 disks - one disk with the proxmox set up, VMs and CTs. And the other disk to be a complete reboot backup. SO, if the first disk fails, the second disk can be used without...

I have troubles backing up an LXC container on PROXMOX VE 9. I do it as a backup job that saves shapshot images on a NAS. Strange thing is that it happens sometimes, not always. Traced error is: 2026-01-10 01:05:02 INFO: zstd: error 70 : Write error : cannot write block : Bad address Backup...

Hello everyone. Im writing this because I dont know what to do anymore. I installed PBS 2 weeks before and tried doing backup test today. Lets just say that 30 GB took 19 hours. My internet connection is not the problem. The PBS is located somewhere connected through Tailscale. It also has SSD...

Hi all, I'm trying to wrap my head around an issue that I've been experiencing for a while now, some progress has been made by accident. My single-node Proxmox server hosts a TrueNAS Scale VM, which has a HBA passed through to it, with 5 disks attached. This hosts, among other things, an NFS...

This post was made in regards to bug report 3086: https://bugzilla.proxmox.com/show_bug.cgi?id=3086 Update: I've updated the code to include an email report to mirror the basics of what the backup job provides and verified that both the log and the email functions as expected. This should work...

Hello, I have an issue that seems to have started after updating to PBS 4.1.0. Backups randomly fail with no apparent reason. PVE Backup logs: INFO: starting new backup job: vzdump --pool CICD --fleecing 0 --mode snapshot --storage PBE_Long_Term --mailnotification always --mailto <email>...

Hello, I’m trying to build a clean backup workflow with Proxmox VE 9 and Proxmox Backup Server, but I’m stuck. Environment: - Proxmox VE 9.1.x - Proxmox Backup Server on a separate physical host - PBS added as storage (type: pbs) - Backup job: Datacenter -> Backup (vzdump) - Backup covers ALL...

Hallo, ich versuche gerade "etwas Ordnung" in mein Netzwerk zu bringen und habe dazu Proxmox VE 9.1.2 auf einem ASUS NUC installiert. Das läuft bisher mit einer VM und einem Container flott und stabil. Ich habe aber von Proxmox VE so gar keine Ahnung und intuitiv zu bedienen finde ich es nicht...

Guten Morgen, Seit dem neusten Update von Veeam auf 13.0.1.180 und der neu Installation des PVE Plugins (v13.3.0.237) können keine Backups unserer Proxmox VMs gemacht werden. Diese brechen jedes mal, beim Versuch via "HotAdd" ein Backup durchzuführen, ab. "SERVER: Failed to perform backup...

Hello everyone, We have a Dell Unity storage system that exports an NFS 4.2 volume to our Proxmox 8.4.1 cluster. The VMs with their disk images on it run normally without any issues. The problems are : - When the Proxmox backup job is triggered, the disk images read by the hypervisors only...

Hi guys, In this post: https://lists.proxmox.com/pipermail/pve-devel/2022-June/053338.html, there is mention of a (future) feature that allows an administrator to base selection of a PVE cluster backup job on a tag - and then of course be able to select a tag. The backup job would then only...

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...
