I've built the current git version for trixie, no issues at all so far. Thanks for fixing the issue!

Packages - no warranties for your data or anything though - are here: https://shell.bzed.at/~bzed/.publish/2025-09-30-bEuCQ1zyb8o/

I had the same problems with Hetzner S3 Objectstorage.

1. Fix - Provider Quirks - Skip If-None-Match header (VMs > 32GB Crash during Backup)

2. Fix - Install 4 patched PBS Debian Files on my PBS Server (Can't finish backup - Log hangs at 100%):
dpkg -i proxmox-backup-server_4.0.15-1_amd64.deb
dpkg -i proxmox-backup-client_4.0.15-1_amd64.deb
dpkg -i proxmox-backup-docs_4.0.15-1_all.deb
dpkg -i proxmox-backup-file-restore_4.0.15-1_amd64.deb

Now it's working perfect!

Best regards Stephan

Did you restart the backup server service? The packages don't do that. Needs to be done manually or just reboot..
 
Then I'm out of clues - maybe just a result of too many slightly different S3 implementations. I'm using it with wasabi s3 and it just works well now.

No, you misunderstood my reply, everything is fine now after I applied the patches to my PBS Server

I updated to the latest version within PBS today - not from the .debs you built bzed. I'm running 4.0.15 from the pbs no sub repo.

Unfortunately the issue still persists. It did seem to get a little further this time. But after about a minute the PBS web UI becomes unresponsive.

Tried with and without skip if non match header. I'm using AWS S3 as the backend.

Is there a difference between 4.0.15 in the no-subscription repo and the packages you built bzed?

proxmox-backup-server_4.0.15-1_amd64.deb 15-Sep-2025 20:05 34535460

the packages in the mirror are older than the patch - I just didn't update the version number because of lazyness :)
