backup

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...

Target audience: Beginners There are no secret tips-n-tricks here, just basic knowledge. Precondition you have an intact PVE installation, be it a single computer or a cluster with several nodes; I am using the current 9.x release you have HDDs which may contain old data - that data will get...

Since the release of Proxmox Backup version 4.0 I'm trying to use a S3 storage brasilian provider (https://magalu.cloud) which is full S3 compatible. But I'm getting the following error while check for bucket: root@pbss3:~# proxmox-backup-manager s3 check mgc-s3 my-bucket-name Error: head...

We did the upgrade from v8 to v9 in our test lab. So far, everything is working fine, but the backup jobs with Veeam are now failing. (We use a VM Veeam worker in Proxmox, which is tied to an external Windows server that host the Veeam backup jobs). I get the following error: "Failed to...

Hiho, wir wollen in Zukunft von Mircrosoft HyperV weg und hin zu Proxmox wechseln. Nach möglichkeit sollten die "Funktionalitäten" so ähnlich wie möglich sein. Aktuell: - viele Kunden mit Einzelserver(Hardware) + 2-5 Virtuellen Maschienen mit Microsoft HyperV - Atera wird als Monitoring...

Hi! Tried searching, but found it difficult to uncover. We are trying to have multiple backup jobs: Backup job #1: Time: 22:00 Occurence: Daily Scope: Most of our VM`s with some exceptions Backup job #2: Time: 03:00 Occurence: Daily Scope: Pool ABC Backup job #3: Time: 05:00 Occurence...

Hallo zusammen Mein System: kleines PVE-Cluster im Rechenzentrum erstes PBS Backup auf PBS und Speicher vom RZ zweites Backup auf meinen lokalen PBS mit smb-Storage auf NAS Gedanklicher Hintergrund: PBS-Storage im RZ hat eine sehr schnelle Anbindung an meine PVE-Server und kann dadurch schnell...

Moin zusammen! beim betroffenen Cluster handelt es sich um einen 8-Node Proxmox-Cluster, bei dem 6 Nodes davon einen Ceph-Cluster bereitstellen. Auf einem der Nodes (vs4, stellt keine Ceph-Dienste bereit, nutzt aber den Ceph-rbd-Pool für VMs) habe ich das Problem, dass sich die darauf...

Hi everyone, I have installed PBS on a VM and have NFS mount with the NAS storage, and I run the backup job for all VMs , the backup moving smoothly with the VMs with Max disk 600 Gib, but the VMs with 1 Tib or more it getting failed with error timeout, command error write_data upload error...

Hi all, firstly I know this is going to be an essay to read but I figured better off answering as many questions as possible upfront. I wanted to get some feedback and suggestions on how to make best use of my setup. I'll list my setup information and what I'm trying to achieve below. I do have...

Hello, I have manually started a backup job and it seems there is no way in the GUI to have a look at the running job. Only after the job is finished, I can see the log in "Task History". Would expect to find it there while it's still running (with a status of "running"). Am I missing...

Hello, I was wondering if it would be possible to have one USB drive (multiple partitions) to backup the VM's in Proxmox and also use the HDD as a TimeShift backup from my Ubuntu VM. I have enough USB HDD's but one drive would occupy also only one USB port. Thank you, Greetings Tom

Hello, can you help me back up the definition? I need to run a backup once a fortnight on Sunday at 2:00. Thank you.
