I haven't found a way to selectively tone down the noisyness and am hesitant to work around it through rsyslogd tuning.

What to do against it?

Hi!
sadly there is currently no way to fix this except rsyslogd tuning as you mentioned.
But we are working on this: https://bugzilla.proxmox.com/show_bug.cgi?id=4646

So well, I investigated this a bit:

PBS doesn't use rsyslogd by default, just systemd-journald.

In theory there is the option to set LogFilterPatterns in the service definition for systemd for the proxmox-backup-proxy.server BUT: Bookworm has systemd 252, and the Option was introduced with 253.

Sure, you could disable journald and switch to rsyslogd, but this is not really recommended, because I would like to keep Proxmox Systems as Stock as possible.

This is a big thing - I have a busy system and the boot ssd's get a lot of wear through this.
