Hi all
I'm in the middle of an Exchange 2013 deployment (CU5) on Windows Server 2012 R2. Currently a two-node DAG, but will eventually be 3-node.
The DAG is working fine and the passive copy is healthy.
I'm backing up the databases with Windows Server Backup. The backups complete successfully, but the transaction log files are not truncated.
Running "Get-MailboxDatabase DB1 -status | fl *backup*" shows the correct date/time stamp under LastFullBackup. The backup is healthy as I am successfully able to restore to the Recovery Database.
Things I've tried so far to clear down the transaction logs:
- Backing up from active and passive DAG node. Same result either way.
- Setting the EnableVSSWriter registry value to 1 (and 0) and then rebooting. I've read that this value is not relevant for Exchange 2013 anyway.
- Changed the backup options to remove the System State. Someone indicated this helped them (no idea why).
- Enabling circular logging, letting the logs clear down, disabling circular logging and then re-running the backup job.
- Cranking up the event log level for "MS Exchange Repl\Exchange VSS Writer" to "Expert". The only additional information this revealed was an ESE event 225 indicating "No log files can be truncated".
- Several reboots of both DAG nodes.
- Swearing a lot (didn't help, but it made me feel better).
Any thoughts on what next to try or how to get further information? I have no hair left to pull out.
Thanks
