I'd like to thank everyone that played around with the previous version of Proximo. I'd also like to PRE-THANK all of you that are going to play with Proximo. The biggest thing I'd like from this community is not at face buyin -- Im asking you to BEAT IT UP AT ITS FACE. I want to bring something...

Hi, für eine ganz spezielle Netzconfig müsste ich einen Apache2 als Reverse Proxy für einzelne Backup Hosts einrichten. Leider verzweifele ich an der Config und habe bisher nur Beispiele für nginx und co gefunden. Egal ob ich ProxyPass auf https://, auf h2:// setzen, egal welche Header ich...

Hi, I currently have 15 PVE Hosts divides in 3 Clusters.. 1 x Main PBS with s Replication Offsite. My question is somewhat related to PBS but not directly. Currently all my VMs are Backed-up no problem bit the Hosts configurations /OS are not. Is there a way to back-them up using the tools...

Hi all — sharing an open-source side project for feedback from people who actually run Proxmox in anger. It's a community project, not affiliated with Proxmox, and this isn't a support request — I'm after criticism of the approach. What it is: Proximo is a small server that lets an AI agent (or...

We noticed backups failing due to the reason: Unable to acquire lock "/var/log/proxmox-backup/tasks/.active.lock" We got a similar error (only at random times) as this thread: https://forum.proxmox.com/threads/backup-fails-unable-toacquire-lock-var-log-proxmox-backup-tasks-active-lock.183852/...

Hi everyone, We have been running PBS with an S3 backend for some time and recently started experiencing memory exhaustion issues that required manual server restarts to recover. After some investigation we would like to share what we have found so far and get some feedback from the community...

Hello, I have an issue accessing PBS backups through PDM. PDM downloads the backup index files correctly, but fails when registering chunks from the .fidx file erreur Log : 2026-06-03T10:30:00+01:00: starting new backup reader datastore 'PBS2-DISK-HDD'...

I'm trying to create an S3-backed datastore on PBS 4.2.0-1 against AWS S3 (ca-central-1). The PBS host has no direct internet egress — all outbound HTTPS must go through a HTTP proxy. From the shell, curl through the proxy reaches S3 cleanly (TLS 1.3 handshake completes, S3 returns expected...

Hello everyone, today I tried to install a Proxmox Backup Server inside a LXC container, since I have only one singele NVMe in my server running PROXMOX VE. I've mainly been following two different approaches from tutorials on the web...

Hello, trying to validate migration from local to S3 using PBS-4.2, I need some clarifications about local .chunks that stay on PBS server. After a backup of 6TB, the .chunk directory of the datastore have 1.7TB. I understand some caching needs, but,this is far too much... I thought ony...

Hello everyone, Is there any way to have retention run based on DATE instead of COUNT? The PBS 4.1.6 Prune settings do not allow for any "delete after 1 month" or the like. The problem with this is that any time a VM changes ID, gets deleted or moves to a different namespace those backups get...

I'm running into an issue with my Proxmox Backup Server setup and now i need some help. I have two external offsite drives configured as separate datastores. I rotate them manually, meaning only one of the two disks is connected to the server at any given time. Each datastore has its own sync...

Hi all I have been backing up 4 vms from a Proxmox server to a proxmox backup server for months now with no errors, over the last few weeks 4 or 5 times a week i get an error (See the log below) only on 1 out of the 4 vms that i backup, i run two backups a day sometimes both error sometimes...

Good day I have pbs vm for all my backups, the pbs syncs these to an offsite pbs for long term storage. my problem is that proxmox hangs on shutdown, due to the pbs storage location being offline. I have seen I can use hook scripts to perform actions depending on vm status, and I have seen...

I needed help managing my 3 Proxmox Backup servers with bi directional replication so I used Claude code to create an MCP ( api server for AI applications ) to help manage things . Here it is : https://github.com/szoran53/pbs-mcp-server

Hi! we are experiencing a consistent restore performance limit of about 2.5 - 3 GB/s when restoring from PBS to PVE. TL;DR: Restore speed from PBS to PVE is capped, independent of any configurations. CPU is not saturated and we cannot identify the bottleneck. Environment Fast system overall...
