backup

Hello, I have a large proxmox cluster but with only three nodes (three physical hosts that run hundreds of VMs). I have a PBS and I would really love to take backups of ALL my VMs nightly. Unfortunately, I can only run the backups in a relatively short period of time (from 23:00 to 06:00) so...

We recently converted from VMware and are wondering if anyone else here is having issues backing up offline VMs with Veeam BR? Do you have a recommendation for a workaround other than powering those VMs manually during the backup schedule? When the VM is offline, we are seeing nothing...

Hy zusammen. Seit ca. 2 Wochen kann ich kein Backup mehr auf den Proxmox Backup Server machen, es schlägt immer wieder fehl mit der Meldung: ERROR: backup write data failed: command error: write_data upload error: pipelined request failed: detected chunk with wrong digest PBS: Version 4.1.10...

I have a Proxmox VE 9.1 production environment with 2 nodes and 1 qdevice (for quorum) using shared NFS storage. During snapshot or backup operations, VMs (especially Windows) become completely unresponsive: VM freezes completely Loses network connectivity (no ping) Console is frozen VM...

Hi all, I'm curious how you handle the 'Freeze/thaw guest filesystems on backup for consistency' option in Qemu Agent. Do you generally keep it enabled by default? In which scenarios do you explicitly disable it (e.g. high I/O VMs or databases)? Have you had any issues with fsfreeze (timeouts...

I’m seeing extremely poor performance when restoring files from a pxar archive with proxmox-backup-client catalog shell and restore-selected. Environment Client package: proxmox-backup-client 4.1.5-1 Installed from: http://download.proxmox.com/debian/pbs-client trixie/main Backup server...

Hello Proxmox Community, I'm currently running a virtual tape library (Quadstor VTL, extended with deduplication) in my homelab, primarily for personal use with Bacula. I'm now looking into expanding my backup solution, or potentially migrating, to Proxmox Backup Server (PBS). I'm aware that...

Hello again helpful community. Today I have a rather easy question for you all! I am trying to restore a VM on a newly installed instance of PVE 9.1.7, however before I can restore it I need to copy over the backup files (45GB). The problem is that ProxMox is installed on a 120GB SSD, leaving...

Hey folks, I have a strange problem. I have one VM in my cluster that just won't backup. No issues backing up other VMs. This is on a three node 9.1.6 cluster that is current on all updates. The VM is a linux machine with a 256GB root disk. QCOW2 format. VMs are stored on an NFS mount from a...

Hi, currently I'm trying to run the backups via crontab. I'll keep the examples as small as possible, therefore I explain my problem using the proxmox-backup-client list command. When I run the command in the CLI directly (logged in as root on my Proxmox server), everything is working as...

Hallo, hier ein Python-Skript um die Konfigurationsdateien und optional auch einen ZFS-Snapshot des rpool separat zu sichern. Vielleicht ist es ja für den einen oder anderen hilfreich oder dient als Inspiration. Features : Pull-basierte Sicherung von Proxmox-VE-Konfigurationsdateien...

Hallo! Ich habe nun endlich etwas Zeit die INTEL SSDs einzusetzen. Die beiden sind jedoch kleiner als die drei Crucials, die aktuell in meinem System laufen. Wenn ich das jetzt nicht durcheinander bringe, dann laufen meine 3x 1TB Crucials als RAID-Z1 und ich möchte die beiden INTELs als RAID-Z0...

I use a Let' s Encrypt cert on both my PVE and PBS servers. This morning I woke up to a bunch of email alerts of failed backups and datastore connection failures. After some messing about I found that the cert on my PBS server had renewed so the fingerprints no longer matched. Was an easy fix...

Hi there, I just started using Proxmox VE in a 2-node cluster (9.1.6) setup as a sandbox for educational purposes. Some VMs already running in the cluster, so far all works well. Looking at options to perform backups of VMs, I'd like to use USB disks as removable storage. On another (Ubuntu)...

Hello everyone, I'm running into a serious bottleneck with my backup strategy. I have a 10-node Proxmox cluster, and all VMs are backed up to a single Proxmox Backup Server. The issue is: I created a cluster-wide backup job selecting VMs by their IDs. When the schedule hits, all 10 nodes...

The Problem : Stop Mode backups on Windows VMs running databases (SQL Server, MongoDB, Elasticsearch, Redis, etc.) fail with: ERROR: VM quit/powerdown failed timeout waiting on systemd After backup, services won't start → Event Viewer shows "Service did not respond in a timely fashion" ---...

Moin! Ich bin neu in der Proxmox-Welt und habe eine Frage bezüglich PBS. Ich setze momentan ein Cluster für unsere produktive Umgebung auf. (Wechsel von VMware). Wir haben bisher für unseren Backup-Traffic ein separates Netz genutzt. Dies möchte ich nun gerne fortführen. Dieses Netz liegt...

Hi, Ich habe gerade festgestellt, dass ich leider alle meine Backups unverschlüsselt an einen S3 Hoster sende. Ich habe ein 3-Knoten Setup, was wäre hier der beste Weg um zukünftig alle Backups zu verschlüsseln und die unverschlüsselten Backups zu entfernen? Sollten alle drei Knoten den...
