I recently upgraded my network from a basic router to a Netgear GS108E Gigabit switch. Backups are now way faster, which is great… but now I’ve run into a new problem.

I run Proxmox Backup Server (PBS) in a VM on one of my servers (let’s call it Proxmox 2). PBS has 100 GB of cache storage since I’m using S3 as a datastore - it stores chunks locally before uploading to S3.

Here’s the issue: I try to backup a VM from another server (Proxmox 1). The VM’s storage is 300 GB, but actual usage is under 30 GB. Everything works fine until it hits 34% (104 GB of data). At that point, the PBS VM and the host server itself become completely unreachable. I have to force power off and restart.

I understand why PBS might crash – my VM has 4 GB RAM, 2 CPU cores, and my internet is only around 60–70 Mbps—but why would the host server hang as well?

Has anyone experienced something like this? Could it be networking, storage, or something else in Proxmox causing the host to become unresponsive when PBS gets busy? Any ideas or advice would be appreciated!

Hello everyone, I’m fairly new to Proxmox and struggling with my homelab setup. I have two machines running Proxmox 9: an HP EliteDesk 800 G5 Mini (Core i7-9700) and a Dell OptiPlex 7070 Micro (Core i3 9th gen). I’m running into several issues and would appreciate your insights.

1. Networking Issue on EliteDesk: I have two VMs (both Ubuntu Server 24.04 LTS) on the same bridge. If I stop or shut down one VM, the other loses internet connectivity. Local access to applications still works. Any ideas on why the bridge is behaving this way?

2. Backup Setup on OptiPlex: I’m running a Proxmox Backup Server VM with Backblaze B2 as an S3 datastore. This is working fine so far.

3. Backup Problems on EliteDesk: I’m using default LVM-thin for VMs. Backups take a very long time and often freeze at 1-2%. Shutting down the VM cleanly afterward is nearly impossible. I’ve tried both Stop and Snapshot modes, but the issue persists. When a VM becomes unresponsive, it triggers the networking issue above. Would switching to ZFS help? If so, how can I migrate without losing any data?

4. Hardware Acceleration for Jellyfin: On the EliteDesk, I’d like to enable hardware acceleration for a VM running Jellyfin (in Docker) using the i7-9700’s UHD 630 iGPU. Can anyone recommend a clear guide specific to this CPU? The Proxmox documentation isn’t very detailed for Intel GPUs.

The networking issue is the most frustrating. Has anyone encountered similar bridge problems? Any advice on fixes or next steps would be greatly appreciated. Thank you!

If I stop or shut down one VM, the other loses internet connectivity. I can still access the applications from my home network using IP address (192.268.x.x).
