Not really a major issue, but I have noticed that my ProxMox VE server makes frequent DNS queries pertaining to my ProxMox Backup Server (8 queries every 10 seconds). This actually makes up ~50% of the DNS traffic reported by my PiHole server on my network which is surprising considering all the smart devices I own and I only trigger backups every 6 hours.
Is this expected behavior or do I potentially have something misconfigured? PiHole is configured out of the box with a low TTL, but I am surprised ProxMox wants to ping the backup server so often when not in use.
