So I need to find a log entry that states something along the lines of "logs for DB_NAME" have been flushed? I will check tonight/tomorrow after the next backup (i have changed the 10PM sched to 3 am)
Thanks, And to all those fortunate enough to have children, I wish you all a Happy Fathers Day Jean-Paul Natola From: [email protected] To: [email protected] Subject: RE: [Exchange] event 218 after backup Date: Sun, 15 Jun 2014 02:53:32 +0000 Then when are they flushed? There are specific event log entries for that. And who is flushing them? There are also event log entries for that. Don’t forget to look into the crimson log. I have seen that the removal of event logs (during the flush process) can cause a major I/O spike. It’s generally easily correlated with the relevant event log entries. What have you done to look at performance? Normal perfmon could be pretty informational here. So could looking at resource monitor during the slowdown.

Failover returned the following error: "There is only one copy of this mailbox database (DB_Name). Automatic recovery is not available.". For more detail about the failure, consult the Event log on the server for other storage and "ExchangeStoreDb" events. To humor myself I created a new DB moved a couple of mailboxes to it, and after the backup the same error was logged. This is single server setup, no DAG involved, using built-in windows server backup Any thoughts on why this only occurs after backup?
