Exchange 2019 DAG Cluster: no transaction log truncate

We have a brand new 2 member DAG cluster with 2 databases in replication. No errors, no queues. Full Backup with Windows Backup VSS and a 3rd party backup software. no errors in eventlog. full backup and Incremental backup do not truncate logs. about 800 MB now. no circular logging. no replay lag time, no truncate log time, Exchange VSS Writer present with no errors.

Is there a threshold? what else can I check? there is only one mailbox at this time, I've tried to produce as much traffic as possible. It should work before production.

But no chance. Please help.

Why two backups?
Full Backup with Windows Backup VSS and a 3rd party backup software.

What do the event logs show when backups run?

Like what events?
With only one mailbox and that level of logs, I dont think you are having a problem just yet, at least it doesnt appear so.

I would test with more users and see how it looks and if the logs get truncated after a full backup.

Hi Andy, maybe I'm just impatient. I will migrate some boxes to see what happens.
